Default Trying to re-code BT moduel, no comms (77).

Using Hex-Com, and I'm getting "to many communication errors". Can't recode the BT.

Right now, I can get and recieve calls, but I can't access the phone book, or display calls on the VIS.

This was a Onstar/BT swap on a 2004 S4. Change the ten pins from the 42 pin Onstar unit to the 54 pin BT module.

I'm fairly certina I want 12877 for coding, but I need to see how to get in.

TIA for your help.

It finally could communicate with the unit, but when I later tried to recode, it lost comms again.

I'll try some more this weekend.
