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.

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.

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.

1. Please check if your car’s AUX has been activated, firstly you can press the AUDIO button from your original CD, then you can turn to AUX function via the right knob, and change the aux volume, make sure it’s not mute.

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”

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

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.

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.
