So it's been a while since installation, I haven't really used it much, but finally after a few MMI and Android auto updates I can say it's working well. I played with the sound earlier, and improved it a lot, but there seems to be one remaining issue which isn't really a big problem, coding gizmos can not see the head unit as the MMI is interrupting. I've read a lot about it on another forum, a thread relating to MMI boxes of all flavours currently at 439 pages

I tested today with Bimmercode: (apologies for big pics)
Then Bimmerlink: There isn't much to be coded on the head unit, so not a big deal, but I have read that an updated MCU may fix it, others have had success.
Anyone else tested for codes after MMI install?
