Kenwood M4524 - Audi A4 2003 : static and power problems.

Hi,

I hope you guys can help me because I don't know anymore...

I've just got a new Audi A4 (2003)TDi with a new Kenwood M4524G car-radio/cd/mp3.

1) The FM reception is OK at the beginning of the ride, but after 10-15 minutes -> lots of static on the FM reception. CD sounds just perfect, not a problem there so it's really with the radio part of the radio, not with the speakers.

Earthing problem ? Antenna problem ?

2) Whenever I turn off the engine, the radio goes dead...OK but I would like it to switch off when I pull my key out of the ignition not when I turn off the engine. Furthermore to get the radio playing again, I've got to turn the ignition so that my heater and everything else starts working aswell (not good for the battery).

I've had my radios (Pioneer, Grundig, Sony) setup like I want in my previous cars (Polo, Golf, Passat) without any special cabling (except for the classic VW

12V trick) but I can't seem to get it to work on my Audi :-(

I've tried the following cabling combiniations : Car red = A4 = ignition Car yellow = A7 = constant 12V Radio red = ignition Radio yellow = battery

A)Settings are saved but radio switches off when ignition is turned with key still in ignition Car Radio red - red yellow - yellow

B) not good since the radio is no longer supplied with a constant 12V to save its settings -> settings are lost. Car Radio red - yellow yellow - red

C)according to the manual this should disable the automatic switching on/off of the radio...but it doesn't :-( it's the same behaviour as in B)

Car Radio red - red red - yellow yellow -

Any ideas ???

(I'm going to ask my audi dealer next week, but it bugs me not knowing.)

Thanks

Simon
