iDrive Issue!!

[RATED_M]

So I have a 2011 M3 with the CIC iDrive (with the multi-function buttons next to iDrive wheel). I have had ZERO issues with Bluetooth connectivity until today, when a friend tried pairing his phone.

For some reason we couldn’t get it to work, and it crapped my whole system! I tried resetting iDrive by holding volume button, deleting car from my phone, deleting all the devices and toggling Bluetooth on and off but it still doesn’t work.

Now when I try to re-pair a phone, it prompts for the pass key and then says “Connecting...” - Bluetooth Audio works but the telephone doesn’t. Strangely though if I place a call on my phone, it shows on the car as it normally would. However, the telephone menu in iDrive shows as if nothing is paired!

Is this a trip to the stealership or can I reboot the TCU?

Oh and then I thought “Restore Previous Version” on iDrive update would be wise, so now I downgraded the modules like an idiot

I previously had:
Multimedia MX-003.005.004
Telephone TX-003.005.006

Now I have:
Multimedia MX-003.004.031
Telephone TX-003.004.031

Any way to get these files? BMW.com/update says my car is up to date

It also won’t show the device under Bluetooth devices on iDrive but shows it as an External Device in Music.

The files can be found if you do some digging.
Or find an an older car for sale online that has the VIN listed and use that on the BMW update site.

Disconnect the battery?

[RATED_M]

I guess it’s not urgent but I don’t understand why this is glitching out all of a sudden. Can I disconnect the TCU? Where is that located?
