Thanks ctuna. You saved me tons of headache in digging into the details on all the forums. I had no idea that it's more than just the head unit.

As far as I know there aren't any Head Units in the aftermarket that use
a fiberoptic interface and there doesn't seem to be a standard for it in car stereo.
Also you should still mount the old system in the car if you want the BMW
programmer to be able to update your cars software, the chimes to work,
and errors not be displayed on your dash do to the missing connection to
bmw SOS .
If you read those links you can see there are a few surprised guys who got that
dynavin unit and had this issue its the same with all aftermarket head units.

Thanks again!
It's not easy to replace the headunit in e9x.
This are findings about it (I have Eur Spec car)
The problems with removal of the MID ( it's not just a headunit).
1) You will have to replace all Amps and probably the speakers
2) You will lose the OEM bluetooth, cd changer (if you have it)
3) You will lose the PDC (sounds cames from the speakers)
4) Steering wheel buttons
5) The dealer wont be able to upgrade/diagnose the software in the car
The solutions... for Alpine Headunits
1) Use aftermarket amps and speakers(beware of size/depth and locations of the speakers)
2) Get Parrot Bluetooth Kit and the Connects2 Steering wheel adapter(CTPPAR006 or CTPPAR009)
3) Alpine Interface APF-R100BM will enable PDC sound for the rear the sensors, they don't have a solution for both rear and front sensors yet.
Connects2 have similar interface(CTRBM001), only for rear sensors also.
Dietz has an interface that uses a separated speaker they claim( i haven't test it yet) that works with both sensors although the sound tone is the same for front and rear.
4) Alpine Interface APF-S100BM, this is an CANBUS Interface with Steering wheel buttons integration , it also have Speed Pulse, Light, Reverse and Ignition signals.
5) There isn't solution yet, just keep your OEM headunit and install it when you need to upgrade/diagnose the car software.
