I recently retrofitted an OEM Bluetooth module in my B7 A4 with a MFSW, color DIS and Symphony II headunit. Everything seems to work ok, but I'm wondering if I've coded the Bluetooth module correctly.

If the radio is on and I hit the voice dialing button, I momentraily get the message "No Funct" followed by "SPEAK" on the DIS. I also get the standard voice prompts from the BT module. If the radio is not on, I simply hear the voice prompts, but nothing on the DIS. Voice dialing works fine. I'm just curious why I'm seeing "No Funct". Is this the intended function? or do I not have the proper coding?

Telephone Controller - 77
Coding: 0001877

I tried coding to 0011877, but that makes the left 'Mode' button to also momentarily display 'No Funct' before normal operation. I also tried 0001677 (which I thought would have been correct since I do not have RNS-E), but that did not change the behavior. Any ideas?

Thanks in advance!

OK. Figured it out. The Symphony II head unit was miscoded.

STG 56 (Radio) was coded to: 1005 . I changed it to 1065 and the mysterious "No Func" disappeared from the DIS. I also changed the coding on the Steering Wheel (STG 16) from 2142 to 4142 to match the coding info on, though the key change was to change the "0" to a "6".
