Yesterday evening I finally got my blue tooth to work on my (new to me Audi A5 Cab)
Audi need a medal for making the Audio options so complicated and as such it makes buying a blue tooth AMI cable damn complicated and very hit and mis
Add to that that most eBay sellers don’t really know what they are selling and don’t describe it correctly
I bought in total three BT AMI cables all stated they where for a 2014 A5 with concert HU and none worked
Some considerable time spent googling yielded that I have an MMI gen 2 interface on the AMI system and as such when it select external audio in (Aux in in old money) it turns off the power
The BT unit then whilst audio connected as no power so doesn’t work
Solution is a little cable hacking to attach a 5v feed from an old usb phone cable. The 5v is now supplies to the BT unit via the usb lead from at the moment the fag lighter socked under the hu and a std aux socket to usb converter
The result is I now have working BT
Not a totally ideal solution as it just provides a BT audi connection. Or no control of the song being played with the cars controls
It’s good enough as Audi provided an SD slot for music and the CD player reads mp3 data so that’s the music side sorted plus dab as std
The BT is mainly for sat nav and music when satnav is needed
Why oh why did Audi need to make it all so complicated
It’s been my lock down project on and off
Hopefully may help some one else who as a latter car from the VAG stable
Cheers. Paul
