Hey all,

I recently bought a 2007 E90 335i, the previous owner had installed the following iDrive upgrade:

https://bimmerdirect.com/products/e6...42953534636285

The unit was working perfectly for a few weeks, but then I had issues with my phone automatically connecting to Apple CarPlay. A factory reset the unit (big mistake) and now my phone automatically connects, however I have lost all audio, iDrive buttons don't work, I can't switch back to the original headunit, I can't access the factory settings (tried a whole heap of passwords).

I've tried contacting Bimmer Direct (the supplier) with no responses.

Has anyone experienced these issues after a factory reset? I've found other people have performed a firmware update, but I have no idea if the update was performed on the same type of headunit/same series of car.

I've attached a photo of the current firmware installed for reference.

Any help would be awesome, cheers.

check the idrive and coding sub forums.

Since this is an aftermarket unit I would back out of the install an go back to stock to see if that still works.

You are not likely to find much support for aftermarket units.

Will do, thanks for the direction.

Wasn't super confident that someone would have the magic answer as aftermarket head units vary so much, but worth asking the question.

Thanks mate
