Hi together,

i have a very strange Problem with my V50, 2005, 90tkm (round about 65000 miles) and the Premium Sound-System.

During a trip on last saturday my Sound System goes off while driving.

# If i push the "On" Button, the Premium Soung Logo comes, but after that nothing.
# The Display shows only the Temperature and Airflow
# if i push the "Sound" Button, i can select bass, treble, balance and so on.

# But the "Menu" Button don't show the Audio-Option (Only Car Options and so on)!
# The Navigation Monitor don't come's out if i press the steering wheel key or use the remote control.
# My parking sensor don't work

I can through out the RTI/DVD from MMM.
I find it interesting that the Sound-System Menu is "deleted" from the "Menu"-Button.
I also reconnect the Battery, but it dont work.

Any ideas? My nerves are quite frayed after the last problems. :(

Many thanks.

Daniel

Thank you for your reply.

The "Amp" ist the AUD Modul?

So i believe i checked it.. i checked also:

ICM: power yes, outgoing light signal yes
MMM: power yes, outgoing light signal no(?)
AFM: power yes, outgoing light signal yes
TMC: power ?, outgoing light signal no
AUD: power yes, outgoing light signal yes
GPS: power yes, outgoing light signal yes

That was yesterday. Today i ordered a MOST Bypass, i hope it will arrive tomorrow.

Okay, today i checked all Modules if power is connected, yes.
All Modules (excepted the TMC) have an outgoing light signal.
I believe only the TMC-Module have a problem (but i don't really know it).

The MOST-Bridge don't arrived yesterday... :mad:

I tested also the Fibre-Line Cables, there are okay, too.

I don't know why, but is it possible that the "MOST Security" is activated and now all devices are offline?

Any ideas?

Thanks a lot.

MOST security will only deactivate things, if one of the integrated parts doesn't aline with the stored codes or is different to the rest. What is the TMC supposed to be?

Oh sorry.

The TMC is the Traffic Message Channel Modul (i belive only in Europe). It works with the navigation system and gives you some informations abuut traffic jams and so on. The navigation system can calculate a new route to bypass this jam.

I believe the TMC is the same as the AFM Modul.

Edit: Here you can see my Menu-Options (Vehicle options, climate options) and the TMC Modul

What i forget to say..

two days ago my car get a new Motormanagement-Update. But after this update i drive home without any problems. One day later the problems began.
Another question: May i need a "online"-Vida and a dice Adapter to make a ring break test?
