I cannot thank you enough for this video. You have saved me $1764.37 from the dealership's prices. Instead of doing this troubleshooting, they said I needed an entire audio system. I purchased a fiber optic loop from the dealership and the culprit was the Satellite Radio module. I plugged in the loop and now I have audio in all components and the SOS System now works. I have a 2007 550i and the procedures works the same. I recommend changing the title to BMW Fiber Optic Troubleshoot, that would increase your views by 20k. I stumbled upon your video through youtube suggestions. Thank you for this video and be blessed.

Very helpful video. Question: I have a 2002 740 iL with a MK3 nav unit and non lighting radio screen. It flashes every few minutes. The faceplate tilts to insert a cassette. The display stays blank but the cassette, multi cd player and radio all play for about 2 minutes then stop. Turning the power on and off it will play for another 2 minutes. If I bypass the MK3 and that is the problem, will the audio display work again? Also, if so, can I leave it bypassed? (dont need the ancient gps) Thanks

I know it been years since u posted this video. But is it possible to not have the Fiber optic wires at the Navigation unit in the trunk? Mine don’t have the optic wire with the harness on the navigation unit.

Hi. Great video. I have a problem with my 2007 750i. I noticed while troubleshooting that all of the modules have a red light going through the fiber all the time, but the amp does not. Should the amp always have the light on like the other modules? Maybe I have a broken fiber? Where is the loop initiated from for the amp? Could a bad receiver cause the fiber not to light to the amp? Any help is appreciated.

Thanks bro good help

hey the radio on a 2002 750i doesnt work. would that mean i need to swap the tuner module?

Hey I tried everything you said on this video with the lollipop and it’s still the same. Only thing I haven’t tried was the radio it self cause I don’t have another radio to test it out. Once a month the front speakers would work for an hour or so then nothing sometimes the display freezes.

Hey I got the same problem on my 2006 750i the CD player works I loads the cd but didn’t have any sound, I have no stations am/fm/sat, I tried connecting my lollipop/most bus to the Logic7, nav, sat, and still doesn’t do anything none of the steering wheel buttons and only thing that works is the climate control any tips?

what can I do. my 750i sounds bad no bass. navigation not working n CD player too. I need help

Hello HiTechElectronic. I just purchased a 2006 BMW 750 Li from a co-workers friend.

Now BMW has finally decided to replace the unit. when i spoke to them today they informed that the parts they will replace is what they describe as (80 Control Display) and (Monitor). Does that sound right as i got a price from another dealer and only for the unit in the trunk. i am confused and don"t think these guys know what they doing. I am now battling with this problem for 5 months, although they are prepared to replace the components at their cost why do they want to replace two components, whereas the other dealer gave me a price on only one.

+HiTechElectronic thx, i changed the ask, but no difference. But, with my other key (key2) is works fine! so i think its car/key memory setting?

What could be the problem if I bypass everything in the trunk but the radio functions still dont come on my screen still looks like yours does in the beginning of this video
