2001 X5 MKIV Screen Blank Help
 

I have a 01 X5 mkiv screen went blank while installling a bluetooth module.
I checked the fuses both in glove compartment and trunk areae and their fine tthe radio is playing the icelink is playing the radio light comes on but not screen.
I disconnected the battery and waited 15min nothing!!!
I remove the dvd nav disc and reinstalled no go !!!.

Whic BT? OEM, Parrot? Parrot needs an extra
part in the 3 series Beemers to function correctly. SOunds like it is miswired if OEM...

Have you tried de-installing the BT module and getting yourself back to where you started?

mkiv screen blank
 

I uninstalled the bluetooth, but still no picture.. I also have the EAS video module with a dvd changer and rear view camera hooked up .and i did notice that the I was able to see the video when i turned on the dvd changer but the picture was very dim, I almost had to scringe my eyes to see the picture but the dvd player does play in background very dimly..
I dont know if it's a wiring issue or a a hardwarwe issue. I dont wanna start buying expensive items like and MKiv or a 16:9 screen ..I just wish one my friends had an oem nav system so i can swap out the above items to eliminate the need to purchase it if that's the case

This happened to me, Check the conectors at the Video Module and the Nav Computer. Unplug all the conectors and plug them back in. If this doesn't work take the Video module out of the loop by pluging the Nav directly into the Video Module harness.

2001 x5 blank screen with mkiv HELP
 

I tried all the above and still no picture. ..Now the only thing that I havent done is take the MKIV out out the loop. Its a sticky situation because its an electrical component and once you purchase it from the the dealer you cannot return it ...So if anyone lives in the South Florida area ( Miami, Ft. lauderdale, West Palm Beach ) I can meet with you anywhere and see if my MKiv nav drive is the problem .. I would also compensate you for your time.
Thanks
