Question about Becker Indianapolis Pro 7950 CD Player

Open Question

Becker/BMW Indianapolis randomly turns itself off and sometimes produces cracking noises on the outputs while playing cd/mp3

I bought a second hand BMW and it came pre-installed with a BMW Indianapolis radio navigation unit. This unit is actually a Becker Indianapolis 7969. The 7969 is an Indianapolis 7920 but with slightly different software for BMW and orange illumination. It's also almost identical to the Becker Indianapolis Pro 7950 except it lacks bluetooth support. But those differences are not related to my problem.

This unit experiences two problems that may or may not be related:

1. After a while the unit turns itself off. Sometimes this happens just minutes after turning on, other times it takes hours. I have it both when playing cd/mp3 or when listening to radio. A press on the ON-button and the unit continues where it left. I took the unit out of my car to test it in controlled environment (stabilized high end 13.8V/10A power supply) but it's showing the same effect. I don't think it's heat related because once the unit turns off you can immediatly power it up again and sometimes it will play again for hours.

2. When playing cd or mp3-cd the unit sometimes
produces "ticking" and "cracking" noises. This happens on the amplified outputs as well as on the line-outs. Sometimes it's just a few cracks every now and then, other moments it's like you're listening to a bad tuned in radio station - except that it's the cd/mp3 playing. When I switch to radio, the cracking is gone. It never happens during radio playback. When I switch back to cd/mp3 the cracking continues. Sometimes it goes away after a while. Power cycling does not seem to have any effect, nor does heat. It happens both when the unit is cold or hot. It's independant of the volume (it's definitely not an overdriven signal). The same problem occurs in my controlled environment with the unit connected to a receiver, so it's not a groundloop or alternator whine related issue.

BMW is of no help. I contacted Becker Europe, but either I completely missed their technical support department or they didn't feel like helping me with a unit that's long out of warranty. I got a reply they can only help me with operation and installation questions. Great... If someone can give me a link / email address to reach Becker's REAL technical support, I'd be grateful.

I don't mind opening the unit, nor am I afraid of some fine soldering. But I need to know where to look - what may cause issues like this.

Thanks for any help you can provide!

I lost the radio code from my BMW Indianapolis!

Go to your local BMW dealership with your vehicle ID # and the Radio serial #. The can look it up or call BMW direct to get it. Other Auto manufacturer's charge 20-25 to do this, I'm not sure what BMW will charge. Hope this helps
