Only thing behind the t6 cd changer is bolted to the chassis, white, 4 inches by 3 inches by two, BMW labels and a bunch of wires.
Thought it was bigger, metal and heatsunk...?
As well as a completely blank Business C53 radio on my 2001 facelift 525DSE, had a fail to start yesterday as well.
Starter cranking well, not even a fire.
Left it 5 mins and she started no prob.
Reading the learned wisdom in here, I think I have the world famous dodgy contact block on the ignition switch. 6 years old, 92,000 miles. and it's showing as a dead radio (although the night illumination works) and an intermittent start fault.
Booked it into my local garage on Tuesday for a diagnostic.
They reckon they see a lot of this , not just Beamers.
If that doesn't work...Dealer time.
I can live without sound, but not with a fail to start.
Just a thought..from what I've read on here, you can upgrade the radio as:
remove the front end, fit a 5 series aftermarket blank plate and fit a front end (with signal output) of your own.
Unless you use an adapter, the steering wheel controls will no longer work.
Unless you use an adapter, the Stock BMW 6 CD changer will not work.
You could use an aftermarket Radio with single CD of course.
The amplifier should work driven by the new front end, possibly with a signal adapter.
Surprised no one has developed a better way (whose name isn't alpine or BMW).
I'll post how I got on.
Thanks for the help and any other helpful advice you guys can pass
Much better than the TIS disk.
