If you've got a question, there's a good chance someone has already asked it. Please take a minute to read through the frequently asked questions below.



1: What is the difference between Android units and "regular"/ WinCE units?

Most Dynavin units use WinCE (older units) or a proprietary OS (newer units) to run the navigation program.... but on some cars there is an option to get android units instead.  This change in hardware makes for a VERY different type of unit but there is much confusion and misunderstanding about what exactly Android means to a car head unit.

The regular dynavin units are best described as "conventional" car stereo navigation systems....very similar to a oem system found in many new cars, very similar to the name brand aftermarket units from Alpine, Pioneer, Kenwood, etc...

Android units on the other hand (like the Avin) are more like grafting an android tablet into a car stereo....they are intended to be flexible and easily modified,  With the added flexibility of android comes the added possibility of issues, issues with android, issues with apps, issues with connectivity. In general these units work fine but they are more complex and require a level of technical ability and knowledge to get the most out of them. If you are willing to spend the time to read, learn, dial everything in, and update and maintain things regularly, android will be a lot of fun for you, if you just want to "Set it and forget it", get a regular/windows unit.  If you do not intend to tether your android unit to the internet you are likely wasting your time with an android unit and would be better off with a non-android based unit.


There are now many "all android" units on the market, they vary GREATLY in quality, some are very good (we carry the Avin units), some are terrible, do your homework!  Or if you are not finding the info you are looking for, email us for clarification.



2: What AC control relocation kit do I need for my E46?

Look at the buttons....if there are no seams between the buttons and they are all housed in the same button housing you need the "single row button" part as shown below.


If you can see seams between the buttons or you have a single button with a "blank" filling in the rest of the are you need a "individual row button" part as seen below.  The number of buttons is irrelevant!  What matters is if there are seams between them or not.


Multiple forum sponsors including myself carry them.  If you have any question as to which part you need, email us a picture of your console and we will let you know what part you need.


3: My BMW has OEM Nav....what do I need to get to install a Dynavin?

If you have OEM Navigation your cars radio is actualy in the trunk! Because of this you will need to purchase the the extension harness (also known as Fakra Harness) that will extend all of the wiring from the radio in the trunk to the dynavin in your dash. The extension cable comes with an antenna extension as well.  You may also need to make a separate connection for the button lighting, See #4 below

4: I installed the Extension harness and my dynavins buttons dont light up!
You may find after installing the extension cable that the buttons on your dynavin dont light up, if so there is one other thing you may need to do.   See the orange illumination wire on the fakra....there is no illumination wire in the trunk plug so you will want to splice that in with the red ignition wire on the fakra, that way the dynavins button lighting turns on when the car is on....OR if you want the lights to dim with the dash lights you will want to splice the orange wire from the fakra into a dash lighting circuit, the easiest place to do this on most cars is the ashtray light or at the stock head unit plug, in most BMWs the lighting wire is the grey and red wire on the blue plug.  ALWAYS confirm this with a test light or voltmeter.


5: Will my steering wheel buttons still work?

Yes. Plug and play.


6: Will the E46 Dynavin work with my E46 HK system?

Yes. Plug and play.


7: Will the E39 Dynavin work with my E39 DSP system?

Yes, ONLY the new N6 units do....but there is a lot to this....a little background info:


The DSP is a proprietary integrated system, the display on the dashboard is just a control unit and display, the amp, radio and all its functions are actually housed in the trunk. Because of its closed nature you cannot remove a part of the system and expect it to still operate.


Because of this there used to be only two options available.  Option 1 was to relocate the dash mounted parts of the system to the trunk and/or glove compartment, info about how to do this can be found here:http://forums.bimmerforums.com/forum....php?t=1553862

The second option was to bypass the factory amp altogether and install an aftermarket amp. This option is desirable if you want to upgrade your sound at the same time that you upgrade your head unit.  Check out the German Audio Specialties crossovers if you want to go this route.

Now with the new Dynavin N6, Dynavin has come up with a way to emulate the oem head unit in a way that keeps the DSP amp active.  This allows the N6 to be plug and play with the DSP system allowing retention of the oem amp and speakers.

If you have a different brand of head unit they WILL NOT work with the DSP system and you will need to do one of the options explained above.

7: Can I watch TV on the Dynavin?

There is a television tuner available but it is a separate accessory. At this point there is only a tuner available for DVB-T markets (Europe and Australia primarily).


8: Do I need anything else?

You might want USB extensions so that you can easily access the USB plugs on the back of the unit once it is installed. The dynavin also has an auxiliary audio video input, there are a number of cables that can be used with the aux in and which cord you might use depends on what you want to connect.  The headphone style aux in plug is the most popular as it allows ANYTHING with a headphone output to be played trh


9: Where can I get these cables?

From J&T Distributing, of course.........but any car audio shop should have the parts on the shelf.


10: I have an early E46/E39 with the "powered" antenna, Will my radio work?

Some BMWs before early 2002 have an antenna that is powered by the factory head unit, when you remove the oem head unit, you remove the power source resulting in sub par radio reception.  The fix is to buy a Metra 40-VW53 antenna adapter, connect the blue power wire on it to the red wire in the dynaivn harness.  This restores power to the antenna and will improve reception.


Since the dynavin N6 now has an oem fakra style antenna plug instead of a standard aftermarket antenna plug, you will also need a second adapter to convert the standard antenna plug on the metra 40-VW53 part to the fakra style plug on the dynavin....

Metra 40-EU20 will do the trick.





11: What do these labels mean on the USBs and which ones should I use?

Older dynavins only....

The DVD USB is used to play music/videos/pictures off a USB flash drive and is one of the selectable sources for the dynavins regular player interface. It is also used to update the firmware.

The GPS USB is used to connect to the windows board for things like the Wifi or 3G modem or the windows media player embedded in the windows menus.


12: Do I need to ground the "park" wire to make video work while the car is in motion?

No, there is a setting in the radio menu called "brake," Turn it off.


13: My Dynavin is very loud and does not seem to have much volume adjustment. 

The Dynavin units have an output level setting to change the output to better match the car's OEM amplifier (if equipped).

On D99 units go to the hidden "Factory Settings Menu" by going into radio settings, select SYSTEM, the press the upper right corner of the screen.  The menu will come up, set the AMP setting to COMMON (or ON depending on your dynavin version).  DO NOT set this setting to OPTICAL.

If your Dynavin is too quiet, do the opposite and set the AMP setting to NONE.


The N6 has a similar feature in the sound menu called Hifi Amp.  Use as necessary.


14: I hear lots of weird noises, static, beeps, etc...
See above.


15: My Steering wheel controls dont work!

Verify that you have plugged in the little black ibus interface box, it  just plugs into the dynavin harness, thats it, the mini USB/second plug on the box is for programming and is not used in the install.

16: What is the best place to put the bluetooth mic?

Many people put them in the stock mic location near the sunroof controls but every car is different, experiment a bit to find the location that works best for you.  The mic is VERY directional so near the rearview mirror, at the front of the headliner, pointing toward you is usually the best option.


17: Will the Dynavin work with a backup camera?

Absolutely, backup cams are probably the most common accessory installed along with a new head unit.  There is a dedicated plug for the camera and a wire that is tied in with the camera power wire so that when the backup camera is activated by the reverse lights, the head unit will automatically switch to the backup cam.




18: The screens gives me a warning message when I try to watch a DVD or video?

Go into the settings menu and turn off the setting labeled "Brake"


19: Why is the time always wrong on the radio screen?

On D99 and older units if you have RDS turned on, the Dynavin will get its time settings from the radio station you are listening to. If the radio station is broadcasting inaccurate RDS time data....your clock will be wrong on your dyanvin! Turn off RDS in the settings menu or call your local radio station and tell them to fix their RDS time settings!


On N6 units the time is set by the gps satellites, good gps reception is a necessity and you must set the time zone in the settings menu.

20: Where is the setting to make the time 12 hour instead of 24?

Dynavin units only display time on the Radio in 24 hour time, On the navigation screens time display is configurable in the navigation system menu.


On N6 units set the region to USA in the settings menu. 

21: Whats with all the different menus?

D99 and older Dynavin have two systems running in parallel. One system runs the radio, DVD/CD, ipod. USB etc.... The second system is running windows and is used to run the Nav program that is located on the SD card....this can be confusing initially as there are three separate menus, one for the radio etc... functions, one for the windows functions, and one for the navigation program functions. Once you spend some time with the unit and understand how it works you will better understand the different menus and how to use them.


22: Does the Dynavin have internet access?

On the old units and android units there was a 3G modem that can be plugged into one of the USB ports and when loaded with a data sim card allows access to the internet through a number of available browsers.  If internet access from your car stereo is something you are after check out the Avin Android units.


23: What is the best way to use the ipod control?

V5 only

Until Dynavin adds a "back" button to the ipod interface, using the touch screen controls can be a bit fidley. Dynavin has managed to enable steering wheel control with the latest firmware so that you can actually control the ipod completely via the steering wheel buttons, this works well enough, use the up and down buttons to move the cursor, the RT button to go back, and a long press of the talk button to select. However I find that the remote control is by far the easiest way to control the ipod while driving. Just use the arrow buttons and the "root" button on the lower part of the remote to move the cursor, skip pages, make selections and go back in the menus


Hold down the MENU button on the ipod screen to go back to the "root" menu and make your selections from there.  Press the right and left arrows on the screen to page forward/back.


Pretty self explanatory....





24: What are all these other programs I keep hearing about?

The regular (winCE) Dynavin will run any number of navigation programs, they just have to be placed on an SD card and if they are compatible the dynavin will run them. It currently comes with a licensed copy of  iGo Primo

Android units have google nav by default but there are a number of other nav options available from the android market.


25: Every time I touch the screen, the music comes from back speakers only.

Go into the windows menu (the one with the lowrider car) go to setup, go to volume, set "keystroke" to "non"
Then start the nav program, go to menu, go to settings, go to sounds, turn key sounds off and turn up the volume controls.

26: When I press the Nav button everything is in the wrong language or even "boxes"....
Do this: (If the video below doesn't appear, try refreshing your browser.)



27: My Dynavin says "navigation software not found"

You will see this if the dynavin is not setup to run the nav program or if there is no nav card in the SD card slot.  The nav program is run from the SD card and you need to tell the Dynavin where to find the executable (.exe) file to launch the nav program.  This "file path" will vary depending on the navigation program being used but the .exe file must be selected so the dynavin knows what program to run.


For instance the version of iGo Primo that we currently sell is located at: StorageCard/MobileNavigator/Mobilenavigator.exe. The older versions of Sygic's .exe files is located at StorageCard/Drive/windowsCE/Drive.exe.  This is part of the initial setup that may be necessary on the unit so see the "install guide and setup" page for more info.



28: I can see the Navigation program but its in italian/chinese/etc...!

Do this: (If the video below doesn't appear, try refreshing your browser.)



29: I did the above settings but every time I turn it off the Dynavin looses its memory!

For reasons I dont completely understand the dynavins sometimes dont hold their memory on the windows settings when new. This usually only lasts a day or two and then it will hold the settings. As far as I can tell there may be some kind of battery backup that needs to charge for a day or two in order for the memory to hold.



Firmware updates


31: Can I update my V1-4 to make it look like a V5?  My D95 to look like a D99?
No, the different versions are different hardware and firmware. The newer firmware is not compatible with the older hardware.





WinCE Setup (D99+ and older)


1: Turn off keystroke sounds

2: Set file path for Nav .exe program (if needed)

3: Start Nav program and autodetect and configureGPS antenna

4: Set radio menu settings to their optimal settings (in my opinion they should all be off)

5: Access the hidden factory settings menu so set your unit up for your region (Radio Settings>System>press the upper right corner of the screen) change Radio Region to the appropriate value and change AMP setting to ON if you car has an OEM amp (all US spec BMWs do), setup the reverse behavior options based on if you are using a camera  if your car has PDC, and if you want sound to mute when using a reverse camera.






Dynavin Android Setup


If you managed to get your hands on an Android unit, good for you! But for best results the unit needs to be set up properly! Doing the following should give you a good start.

Once your unit is plugged in and running, play around with it for awhile to figure out the basic functionality so the following makes sense....


1: Press the MODE button to to the source screen, press the settings icon in the lower left (gears). I prefer to uncheck all four options:
Navi Sound....makes it so that android sound comes from all 4 speakers instead just the front (remember that the android part is intended to run the Nav program)
RDS....radio data system....will display radio station and song data, thats nice but it also transmits time data and when your radio station screws up the time it will screw up your clock.
Beep....Self explanatory.....makes that annoying beep go away.
Brake....makes it so you can see video without getting a warning message.

2: Go to the source selection screen again and choose AUX as your source, then take the remote control, hold down the 9 button to bring up the factory settings menu. You will see some settings.....change the radio region to USA1 and if you have a car with the OEM amp in the trunk (all US spec cars do) you will set the AMP setting to ON. Once you are done setting it just let it sit for a minute and the menu will "time out" and go back to AUX.

3: Now to access the android side of the unit you will use the NAVI button, it will toggle back and forth between the radio side of the unit and the android side. Almost every app on the android side has its own volume control that is controlled by the volume icons on the status bar at the top of the screen, if the volume settings for any given app are too high the sound will be be distorted, turn them down to a moderate level for best results.

4: The android part of the unit gets its time settings from the GPS receiver, in the time and date settings you will need to uncheck the "Automatic" time option in order to set your time zone but be sure to recheck "automatic" before you leave this menu so that it will continue to automatically get the time data from the satellites.

5: After you set up a wifi connection between your dynavin and wifi hotspot, I find that it connects most reliably if the hotspot is active when the dynaivn starts up, so I activate the hotspot on my phone as I am walking up to my car. Then when I start the car, the dynavin starts, the android system boots up, scans for wifi, and wifi connects. It takes a couple minutes but it does this fairly reliably. If you start the hotspot after the unit is on the unit may or may not automatically connect. In this case I find that if I toggle the wifi off and back on in android, it will connect after a minute or two. Of course, this is wifi, so your results may vary depending your your wifi source, what works best for me may not work best for you!


Android Firmware Re-installation: If for any reason you want to re-install the Android OS.... (remember this will wipe out all of your apps and settings)  Do not do this unless you know why you are doing it!

Go to dynavins website and download the firmware: http://www.dynavin.com/android.php

Make sure the entire thing downloads....its been my experience that this download often hangs....

Once it is downloaded, unrar/unzip the download.  (right click>extract all)

Place the  files directly in the root of the SD card that came with your dynavin (this is critical, no other SD card will work for this process)

Place the SD card in the dynavin and turn the unit on. The unit will automatically begin to update.  Once it is done updating it will prompt you to remove the SD card and restart the unit.

It will take a long time to boot up the first time after installing the firmware (about 4 minutes).

Once you are satisfied that it has updated, delete the firmware files from the SD card so you can continue to use it.
