I'm considering the option of going aftermarket head unit rather than retro fit iDrive...
I've got a couple of questions...
1) Will I lose anything (parking sensor beeps, chimes, settings menu etc) if I removed my oem head professional head unit?
2) What other kit will I need such as harness, fascia etc other than the headunit?
3) How easy is it to install (Couldn't find no DIY in search)
4) What do people think about this head unit?
