Before you change a head unit in a BMW

You should be aware of all the side effects and problems.
Also most common stereo shops will mess up your car.
You need to know which of the three BMW car stereo's you starting
out with. If you have logic 7 you will loose the logic 7 amp because
of the way its hooked up. With Hi Fi it will be possible but still has
major side effects.

The problem list
error from the BMW SOS if you have it
BMW cd changer will no longer work if you have it
PDC will no longer work if you have it.
Why because these things are hooked up to or talk to the BMW
Head Unit.
If you take the car into BMW and they need to hook it up to there
Diagnostic computer it will not be able to repair the car until it see's
the original configuration of the car including the BMW radio.

I'm not suggesting Dynavin its just it's well covered and the problems
are the same as with any aftermarket head unit.

Whatever you do don't dispose of the old head unit because you
may need it when you need repairs as the BMW diagnostic computer
will not be able to change values in the sub modules if you need
a repair without a BMW Head Unit installed in the car.

It beeps when you back up the frequency increases as you get closer.
Its and option not all cars come with.

thank you sir very much apreciated

So if I have none of these then there is no problem?

The BMW repair computer at the dealership will not be able to make
repairs to your car unless you remount the OEM Head Unit
or move it to the trunk or somewhere with it still hooked up to the can bus and with power running to it.
The guys with 335's had to do this a lot when they had HpFp problems . One guy showed up on this board with a 328 he had to have something replaced in his anitlock break system it needed calibrating from the BMW computer but since he bought the car used with and aftermarket head unit in it this could not be accomplished. I think the guys on the coding board have a way around this but BMW will tell you to return the car to stock condition so there repair computer won't choke.

[bgill76]

So I won't have any problems if I keep the stock headunit plugged up?
