Solution For No Sound After Installed BMW E60 Android Head Unit

Are you trying to install an aftermarket BMW E60 Android head unit but no sound comes out from music or video playing while testing? The sound from factory radio and CD player works well, just no sound from Android screen. Don’t worry, if you follow instructions provided in this post, you can get sound with this solution.

How To Find Out The Exact Problem?

  1. Check original AUX

    Firstly you should know that the sound from Android screen transfers to car speakers through original aux mode, so if there’s no sound, the first thing you need to check is your aux, does your aux work well now? You can use a aux cable to connect your phone with the aux jack in the armrest or below  the radio unit, then play music with your phone, and check if the sound from your phone comes out from car speakers, if yes, that means your aux works now.

  2. Check original 3 AUX wires

    The next step is checking Aux wires from original wiring harness behind the factory radio and CD. Make sure your aux wires match the new aux wires in the same position. Few BMW E60 comes with aux wires in different position or without aux wires from the plug behind the radio. You can check our aux wires from our plug as below:

    wiring diagram

    Our aux wires are with red, white, and black color, 3 wires in a group, you can see below picture:

    aux wiring diagram

Compare your plug with our new plug to check the 3 aux wires in the same position. If your aux wires are not matched, or your plug does not have aux wires, then you can try our solutions.

This picture shows you the original wiring diagram from BMW E60 E61 radio module M-ASK and CCC.

BMW E60 E61 wiring diagram

Check connector B, pin#2 is AUX Left audio, pin#7 is AUX right audio, pin#8 is AUX ground.

So you can check if your aux wires are in the position as above. If not, you can move them to the same position as above. While if there’s no aux wires from your plug as below:
not have aux wires from e60 plug

If there’s no sound after installation of BMW E60 Android head unit, here are 2 solutions for you.

First solution:

This is easier, you can buy a aux adapter cable from us. So you can connect it directly with your aux jack in the armrest or at the rear of armrest, which means our unit connects to your aux directly without modifying wires.

Second solution:

Since you have already known how does the sound work, and know you will need to connect your aux with our aux wires, you can also splice our 3 aux wires from the blue plug and connect them with a aux cable.

aux plug
Splice red, white and black wires, connect them with a cable as below. Then connect that cable to your aux jack.
aux jack in the armrest

Feedback from one of our customers in Norway:

I sort thing out. Must mods the black, white and red plug from your unit harness into a aux cable. Then connect its to my aux in inn the armrest. I got sound in that way.

For customers in Dublin, Northern California, USA, close to San Francisco, we have a recommended shop for you. They have already tried and proved the second solution successfully.

Mercedes Benz W204 Screen Upgrade – How to Switch Android Screen and Factory Menu

Most Mercedes Benz C-Class W204 comes with a 5.8″ small screen above the radio and air vents in the dashboard, some are with a large 7 inch screen. No matter which screen size your car has, you can upgrade the W204 screen with an aftermarket Android screen. The factory W204 radio keeps working after upgrade, just replaces the factory screen for installation.

mercedes w204 screen upgrade

The W204 screen upgrade with OEM looking, with both systems, old system and new Android system.

Due to the different resolution from factory screen, the switches settings from the main unit are different. Normally for Mercedes Benz W204 with factory small screen, the settings for switches of the main unit should be 2, 4 on, 1, 3, 5 are OFF.

switches settings

About these switches:

  1. Only turn it on when you test it with external 12V power, if you install the W204 Android screen in car, please remember to turn 1 to OFF before you connect the plugs.
  2. If your car has small screen, you need to turn 2 to ON, so the Android screen can display factory menus normally. While if your W204 has 7 inch screen, 2 should be OFF.
  3. Always should be OFF for 3, it’s the setting for another model, not for W204 model.
  4. Regularly, if you turn 4 ON, you are able to switch from factory menu to Android menu after you activate and enter into factory aux mode. After you enter into aux mode, but the screen does not switch to Android menu, you can turn 4 to OFF, when the screen displays aux mode, then you can try to long press the BACK button or C button, so the screen will switch to Android menu.
  5. If your car comes with factory reverse camera, then you can turn 5 to ON, so the screen will display factory camera image while reversing. If you need to install an aftermarket back up camera, then you need to keep the 5 to OFF.

If you order the Mercedes W204 Android head unit from us, we will confirm your car information with you and set the correct switches for your car before the shipment, so that you don’t need to set it again.

Overall, after installed the W204 screen upgrade, you can switch between the factory menu and new Android menu.

Mercedes W204 with factory small screen:

  • Correct settings: 2 ON, 4 ON
  • Factory menu switches to Android menu: just activate and enter into factory aux mode, the screen will switch automatically, if not, then turn OFF 4, then long press BACK button or C button to switch.

Mercedes W204 with factory 7 inch large screen:

  • Correct settings: 1, 2, 3, 4, 5 ALL OFF
  • Switch to Android menu: long press BACK or C button(Regularly just long press BACK should be ok, but we also met a w204 should long press the C button which is a little different.)

Questions You May Have After Installed a BMW Navigation DVD Unit

Here are some common questions you may have when installing or after installed a BMW navigation DVD head unit in your car, and you can find out answers one by one. 

  • Failed to turn on the unit
    All cables are connected, but failed to turn on the unit, firstly check if there’s a CAN-BUS decoder not connected, then check the wiring diagram at the back of the unit, try to find out the red ACC wire and use a multimeter to measure the voltage to see if it’s about 12V. Sometimes the cable may be loose, the unit was well tested before the shipment, so this problem rarely happened with the unit itself. Secondly, your wiring harness may be a little different in pins, so you can compared the pins from factory harness to the new plug and see if they are matched, if not, just move the wires to the correct pins from the new plug to match the factory harness.
  • Steering wheel controls not work anymore.
    For some models of BMW navigation DVD units, there’s a CAN-BUS decoder included in the package to support steering wheel control, if steering wheel control does not work after installation, you should check if you have connected a CAN-BUS decoder and make sure it was connected well.
  • Touch screen not work
    For WinCE system BMW navigation units, touch screen can be calibrated in settings > touch. For a capacitive screen, normally touch screen is responsivie with your finger, if touch screen not work at all, the flat cable between the screen and main board may be loose during the shipment, so you can try to dismantle the unit and check cables inside of the unit, make sure all cables inside are well connected.
  • Wating for GPS signal
    When you use GPS navigation function, the maps show a message “waiting for GPS signal”, firstly you should make sure the car is outdoors not in the house, because in the house the unit may not be able to receive GPS signal. Secondly please check the GPS antenna to see if it was connected well, you can put the GPS antenna at top right coner of the dashboard to receive better GPS signals. Thirdly, check the settings from your maps, if you use IGO Primo GPS maps, you can check the sys.txt file inn the root directory of the GPS card, pay attention to the baud rate and port, usually the baud rate should be 9600 and the port should be COM2 for most aftermarket navigation DVD head units.
  • CD or DVD disk can not fully go into the DVD player
    This is most probably you did not remove the 2 screws which was used to protect the DVD loader during shipment, you should remove these 2 screws before you install the unit in your car, if not, DVD player will not work. Don’t use brute force to push the disk into DVD player.

Buying and installing an aftermarket BMW navigation DVD head unit from dvdgpsnav.com, you will not only get good pre-sales service, but also excellent after-sales service. We double test every unit before the shipment to make sure the head unit works well. Need to find a navigation DVD head unit for your BMW?

Installation of Aftermarket DVD GPS Head unit for 2007 Mercedes-Benz ML350

It has always been the desire of many car enthusiasts to own a professionally designed head unit with the best features that will make it stand out alone in the market. Different vehicles have different dashboard so the aftermarket DVD GPS head unit is also different. While installation is also a little different, especially for these cars have fiber optic amplifier. For example, if your car is 2007 Mercedes-Benz ML350 with harmon kardon sound system and fiber optic amplifier, this Mercedes Benz ML GL DVD GPS can fit your car, there are two different installation methods for you to choose.

2007 ml350 factory head unit
2007 Mercedes Benz ml350 factory head unit
Mercedes Benz ML GL DVD GPS Navigation head unit
Mercedes Benz ML GL DVD GPS Navigation head unit

As the aftermarket head unit does not support fiber optic amplifier, so the fiber optic amplifier will not work with the new unit after installation, so what do i have to do?

Firstly, you can splice 8 speaker wires to connect your 8 speaker wires for each car door speaker directly to get sound and by pass the fiber optic amplifier, there’s a long cable with 8 speaker wires included in the pacakge. With this solution you will not need to purchase another amplifier, just check a wiring diagram at the rear of the new DVD GPS head unit and then you can find out 8 speaker wires.

The other method is by connecting the head unit with another amplifier which is non-fiber optical. There’s a lot of work to do for this, so you can try to take it to a professional car stereo shop to install for you. Thanks to N. Elias, who is a professional installer and successfully installed this Mercedes Benz ML GL DVD GPS with another amplifier connected. You can check what he did as below.

It turned out that the harness only powered a few of the speakers so i went to mercedes benzs startekinfo website and got the pin configurarion of the factory harness and i ended up having to cut the wires and rewire them to two 6channel amplifiers that were 600 watts. The sound quality is actually better than the original amp. I completely removed the original amp and installed two aftermarket amps in its place.

There are 12 speakers in all. Front center, left front tweeter, left front midrange, right front tweeter, right front midrange, back left tweeter, back left midrange, back right tweeter, back right midrange, rear left tweeter, rear right tweeter, subwoofer. I looked up from the original harness which wires went to which speaker and matched the front speaker wires up to amp1, then the rear speaker wires to amp2. Then i used the preamp signals from the head unit to go left and right. Front left/right signal went to amp1, rear left/right signal went to amp2. There were also filters on each channel on the amps so for tweeters i only let the higher frequencies pass, the mids some of both and the subwoofer low frequencies. It involved taking apart alot of the vehicle. I luckily also have a mercedes benz star diagnosis unit and was able to reset my seat airbags. The driver and passenger seats both need to be removed to get to the factory amp and battery. I have worked on cars alot but this would probably not be an easy task for a beginner. The headunit has alot more functionality now though than the original and i can add devices easier and cheaper. I will be installing a rearview nightvision camera soon and it is much cheaper than the mercedes solution.

It was successfully installed. I did have to install a new amp, but it turned out be even better than the original in terms of audio quality.

If you still have a question, you can contact us freely.

Solution for No Sound of BMW X1 GPS navigation unit – Installation Tips

If you are installing an aftermarket BMW X1 navigation head unit, and found there’s no sound after installation, there are some steps you can follow to get sound for your new unit. Firstly please understand that in order to transfer sound from the BMW X1 GPS unit to your car speakers, your car should be with AUX function and it has been activated and works well now, the sound is transferring from the unit to your car speakers through your car’s AUX function.

Question 1: There’s no sound for navigation function.

1. Firstly please check if you have connected a small speaker coming from the package, this small speaker is used to get sound for navigation if you are using the original car radio or CD player, see the below picture, you should connect this small speaker with a small plug.

speaker

2. If you have connected this speaker correctly but there’s still no sound for navigation function, you can check settings > navigation from main menu, you should tick this small speaker, if you did not tick this, there will be no sound from our small speaker, so you should tick and choose it.

tick

When you listen to your car radio, then you can click “NAV” button from our controller to enter into navigation,  so that you can hear the navigation sound from our small speaker.

Question 2: There’s no sound for USB media playing.

knob

knob2

activate aux mode
The above photo showing the factory aux has been activated and the aux volume has turned up.

3. After you have done the above steps,  if there’s still no sound from USB function, your aux cable should not be included in the plug from the back of your factory unit, so you should find your aux cables, and then connect them to our plug, so that your aux works and there’s sound. You can check our plug with aux cables as below:

auxcables

The red cable from our aux cables is for Left audio,
The white cable from our aux cables is for Right audio
And the black cable from our aux cable is for GND.

You can check the factory plug with 3 aux cable as below:
factoryaux

While if your car’s plug from the factory unit is as below:

noaux

  • Then you need to find your aux cables(if your car has aux function) to connect with our plug’s aux cables to get sound. Do not buy aftermarket BMW X1 GPS unit if your BMW X1 does not have aux function or the aux function does not work.
  • Or you can use the other audio cable with aux adapter plugs(included in the package), see below photo:
    audio-cable
    Check and download this document to learn how to use this audio cable.

By the way, if your car has 2 fiber optic cables from the factory plug, then you need to move them to our plug to get factory radio working, see below pic:

how to move fiber optic cables

Note: If you did not move the fiber optic cables from factory plug, there will be warning sound coming out.

Make sure you check the installation manual for this BMW X1 navigation gps unit before installing it, there are more tips from the manual.

How to set gps path for aftermarket car gps navigation?

More and more car owners are interested in upgrading the factory stereo with more functional and modern aftermarket head unit which comes with gps navigation system built-in. That’s because the original navigation is too expensive and it does not have so much function as the aftermarket navigation unit which has many other functions like USB, SD, iPod, DVD, RDS, and so on, while the gps navigation function is the main consideration for most buyers.

Normally the gps navigation system is built-in, and gps maps are in a SD card which should be put into the GPS card slot which is usually at the front panel of the gps unit. If you have got a SD card with maps, then you can insert it into the GPS card slot, not the other SD slot, the SD slot can not read gps maps. Then you can go to main menu, find settings, click it, and look for navigation menu or gps menu, then click it to enter into gps path settings, then choose the exe file from the gps files, save it, that’s all. Let’s show you some pictures for your reference, all pictures are from our BMW navigation system.

1. Turn on the gps unit, back to main menu, find “settings”

gpspath_1

2. Click settings, then you will see another interface for all the settings of this gps unit

gpspath_2

 

As you can see GPS setup, this is the place to set gps path, the gps monitor shows the gps satellite signal, you can see how many gps sattlite is connected with this gps unit from GPS Monitor. Only if your car is outdoor can you receive better gps signal, if your car is in the house, the gps signal is weak or not at all.

3. You can see navigation path settings as below. If your map is IGO, the final gps path should be IGO.exe or IGO8.exe or Primo.exe. The after market gps navigation units can also support other maps like Route66, Papago, Tomtom, etc, the map should be compatible with Wince6.0 system and 800*480 resolution.

gpspath_3

 

After you set all done, you can turn to GPS then you can use gps navigation right away. If you have a problem for gps navigation system, sometimes there may be an error from maps, then you can get another map, especially if you download maps online, make sure there’s no error while downloading and compressing all files. If the maps are ok and you still can not use gps function, the SD card may be defective, so you can try another SD card and copy the same map files.
