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 - <unattached>

Any ideas ???

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

Thanks

Simon

Did you use a signal seperator/preamp interface? ie.

The above refers to 'bee sting' aerials, but also applies to integral
glass aerials on a lot of Audis.

The ignition switched feed on that age of vehicle is almost certainly
CAN Bus. To connect an aftermarket radio so it switches on key
removal, you'll probably have to locate the switch feed on the back of
the ignition barrel. Depending on the radio's ignition switched feed
current consumption, you may well then have to fit a relay in line to
give the feed sufficient capacity.

Okay, that's probably it. I'm going to check this out.
Strange that I didn't have any problems in my VW cars...
