I have used the AV inputs in the tv module to run a simple Bluetooth receiver that worked very well. (Fusion BT-100) But this allowed no data to be transferred from the phone to the car for music or calls. And touching the phone is a $1000 fine here while driving.

So I spring for an Apple CarPlay retrofit. Much more useful and about the same price as AMI and uses factory MMI controls

As for the Update cds, the first pass of the Bluetooth CD wipes the module, and the second pass installs the correct software. So you have to run it twice.
Give that a go too.
