Hello bwj,
as we stood in close contact via mail, regarding this issue and you asked me to respond to your post, i will do so here to let others learn from this issue.
We first tried to change the cable and the CANBUS Adapter in the front of the car, this didn't help. After that we tryed to do a update without any luck.
So now it is time to focus on your DAB unit. Witch is installed between the AVANT2 and the Car connection.
Please disconnect the red marked cable, for it is not part of the AVANT2 unit.
You will have to connect "1" with "cable to amp" to disonnect the DAB as i can tell from the picture:
This is the AVANT cable 1:
please post your result, the AVIN should work perfectly without the Adapter in between. (if nothing else was changed by your assembling shop)
If you post further detail for the DAB unit, i will try to help implement it to your system correctly, if possible.
Greetings
Robert
