I have a early 05 A8 with analog OnStar and no Bluetooth.
I got an mObridge M2 Pro Most recently ... and I can't get it to work.

used VCDS to disable Telematics (75) and enable Telephone (77).

Power/ground seems easy enough. Inserting into the MOST bus seems easy too -- follow the arrows.

But when I connect it, the MMI refuses to boot. VCDS says the Telephone has an electrical fault and there are optical faults at the CD-changer and the Telephone.

I have quadruple checked everything. I'm baffled.
Is there a trick I am missing ... or did I get a bad box ?

thanks.

What MMI software version do you have? Must be at least 3360, ideally the newest version 4610.

No need to disable telematics as it doesn't interface with the MMI.

I read those ... still confused.

I upgraded to 4610. Does it matter that I upgraded before enabling Telephone (77) ?

mObridge suggests disabling Telematics (75) for the M2 Pro ... so I did.

I would contact mObridge.

It should just work then. You've coded module 7 with "2" to enable the phone right?

If it still doesn't work, then I'd also go with it being a faulty mObridge unit.
