I've just posted on the original (big!) thread but as this is Carsara specific I hope someone can help/advise me please. I've followed this thread with interest - thanks to Cyberdemon and you all for making this such a helpful resource

I run a 2012 F10 Alpina (sorry ) with CIC and decided to take the plunge with a Carsara box and installed it today. It's almost there but I have the exact same problem as PACarGuy - after 1 min I get the same error message, see image.

Like your E9* installations, my car did not need the iDrive loom - the controller works the screen perfectly. A# is connected to B#.
I've tried connecting L# to B# but then the display does not come on at all.
I've also tried connecting the IDrive loom in case this works, but nothing with that either.
The most successful option is A# direct to B# with L# not attached to anything, but I get this error message every 1 min.

Any suggestions guys? I wonder if something is needed into the feed L# and this is tripping the message??

One other quirk is if I turn on the radio with the ignition off, before the install I'd get the iDrive screen switch on and radio would play. Now radio plays but I get no iDrive screen, only an orange screen.
But if I turn the ignition on, normal BMW splash screen and iDrive screen loads as normal.

Other than this it seems to work ok. I've emailed carsara and hope they can help, or I hope someone can advise me on how to solve?

On audio, like you guys I've tried to code out AUX from the console to HU only but I only get the first code option CDMM_AUX_HU - I've changed to "aktiv"
But I can't find the USB_SINGLE or DOUBLE
Currently I am only getting audio if I connect the aux wire into the console (so it's still live despite the one code change I made)

Any advice would be gratefully received
