1. Before you Buy/Pre-installation


1a: 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/radio 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/radio: 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. 



1b: Which AC control relocation bracket do I need for my E46 without OEM navigation?

Look at your car's buttons. If there are no seams between the buttons and they are all housed in the same button housing, you need the "single row relocation bracket" as pictured below.


If you can see seams between the buttons (as pictured below) or you have one button with a "blank" filling in the rest of the area, you need an "individual row relocation bracket".  The number of buttons is irrelevant but what is crucial is whether there are vertical seams between them or not.


If you have any questions as to which part you need, email us a picture of your console and we will let you know!




1c: My BMW has OEM Nav. What do I need to install a Dynavin?

If you have OEM Navigation in your BMW E46/E39/E53, your car's radio is actually in the trunk. On the appropriate Dynavin page for your BMW model, select "w/ OEM navigation (includes extension cable)" under the "Current Audio System" drop-down menu.

The extension cable (a.k.a "Fakra cable") extends 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 #1d below).

Be careful to note the location of the battery cable in your car, running the extension harness near the battery cable can cause noise issues.  Standard practice is to run the signal cables (including the extension harness) down the opposite side of the car from the battery cable.



1d: I installed the extension harness and my Dynavin buttons don't light up! You will find after installing the extension cable that the buttons on your Dynavin don't light up, if so there is one other thing you may need to do.There is an orange illumination wire on the extension cable....but there is no illumination wire in the trunk plug.  You will need 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.

1e: Will my steering wheel buttons still work?

Yes! A CANBUS/iBus adapter is included with each unit to handle the steering wheel control messages from the car in addition to other functions. Just plug it in!

1f: Will the E46 Dynavin work with my E46 HK system?

Yes. Plug and play.



Back to Contents


1g: Will the E39/E53 Dynavin work with the DSP system?

Yes, ONLY the new Dynavin N6 units do.

Note: All M series E39s and E53s have DSP. Another way to know is if your car does not have stock navigation and your stock stereo has a DSP button on it, then it has DSP. If you're still not sure, get your VIN and go to

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.  Due to the architecture of the DSP system, there are some limits to the functionality of the system; for instance, the fader is not adjustable (as the input to the DSP amp is 2 channel, not 4) and the interface with the stock DSP amp requires a very specific setup procedure to ensure even volume output between sources.


More about DSP:

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 stock system to the trunk and/or glove compartment, info about how to do this can be found here:

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. 

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

1h: 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).

It does play DVD movies.

1i: Do I need anything else?

You might want the USB extension cable so that you can easily access the USB plugs on the back of the unit once it is installed. This allows you to charge your phone or plug in a flash drive loaded with your music. 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. For example, the headphone style plug is the most popular as it allows ANYTHING with a headphone output to be played. Lastly, since the Dynavin is reverse camera ready, you may also want the reverse camera. These items can be purchased from our accessories section.

1j: Where can I get these USB and auxiliary cables?

These cables can be purchased from our accessories section.

1k: 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 Dynavin 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.

1L: Is the Dynavin and truly "plug and play"?

Yes! These Dynavin units come with wire harness adapters that match the factory wiring and all the accessory parts needed for standard functionality. They are cosmetically and physically matched to the vehicle in order to fit and appear stock with minimal installation required. Except for a few minor exceptions, they fit without modification to the vehicle.

Various accessories are also available, backup cameras, panel mount cables, tuners, etc. that may require more extensive installation.

1m: Does the Dynavin support Sirius XM satellite radio?

No. These units do not directly support satellite radio; however, it is possible to run a separate stand-alone tuner with the audio feeding into the auxiliary input on the head unit OR get the Sirius XM smartphone app and stream the audio to the head unit via Bluetooth.

2. Installation


2a: 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.



Back to Contents


2b: 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.



Back to Contents


2c: 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).

If you have an E39 with DSP, go to the "Sound" menu icon > DSP Setting and adjust the slider higher. This will help regulate call volume that is too loud. Do the opposite if too quiet.

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.

2d: I hear lots of weird noises, static, beeps, etc...
See above.

2e: My steering wheel controls don't work!

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


Back to Contents


2f: What is the best place to put the external 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 rear-view mirror, at the front of the headliner, pointing toward you is usually the best option.

 And, yes, you must install it for the Dynavin to be fully functional.


Back to Contents


2g: 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 standard video 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. Most aftermarket backup cameras are compatible with the Dynavin.

2h: Why won't a disc, CD, DVD go into the CD slot?

Some of the units are shipped with two shipping "protection" screws on the top of the unit as pictured below. Dynavin has begun phasing these out as they have redesigned the CD drives but they have not yet removed the warning on the top cover. Check the top of the unit to ensure these are not installed and, if present, are removed before installing. 

Before reinstalling into your dash, we recommend inserting a disc to ensure it is working correctly.

2i: This plug doesn't seem to match the plug in my car.

Every Dynavin unit comes with the appropriate wire harness adapter to match your car. Some units come with 2 or more plugs to match the variations possible in a few given vehicle applications. Look closely at each plug. It may take trial and error but one of them WILL match up to your car.

If you have a BMW and are using the extension harness, the short adapter harness plugs into the radio plug in the trunk area. Then the extension harness plugs into that and is run to the dash where it plugs into the back of the new head unit. You are no longer using the stock radio module or the CD changer; you are simply connecting the extension cable to the car plug (sometimes a blue end) which is  in the trunk for your BMW with OEM navigation. You are bypassing the stock radio module.

3. Operation


3a: The screen 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".



Back to Contents


3b: Why is the time always wrong on the radio screen?

On older D99 and earlier 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 Dynavin! 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. (See image below for your time zone setting. Daylight Savings Time is depicted below. Add -1 for standard time.)

Visit to search by specific location.

3c: Where is the setting to make the time 12 hour instead of 24?

Older 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. 


Back to Contents


3d: What's with all the different menus?

There are separate menus for the stereo portion of the unit and the navigation portion of the unit.  Time settings and a number of sound settings may be fount within each. 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.



Back to Contents


3e: Does the N6 Dynavin have internet browsing?

No. Newer Dynavin units do not have internet browsing as they are more conventional, radio function focused units.

4. Navigation


4a: I press the navigation button and nothing happens!

On N6 units the Navigation Data SD card must installed in the nav SD card slot or the nav button will not respond.

4b: My E9X Dynavin loses its settings every time I turn it off!

Unlike most cars the E90/92/93 BMW 3 series does not have a constant power "memory" wire in the factory radio plug.  Dynavin provides a power wire in the new wire harness that is to be run to the car's positive battery terminal.  This wire MUST be connected for the Dynavin to operate.  While it may seem attractive to try to connect to a constant power source in the fuse box it is not recommended.  Most of the circuits in the fuse box shut down after 20 minutes.  Running to the power wire to the battery is the least time consuming and most foolproof.
