It sounds like the car can’t see the module; no divorcing is necessary; that info is stored in the cd changer not the car. If the bluesaab is working right then the car just sees it and it works right away.
So I would look at the canbus section if the microcontroller has code and is working correctly.
Does the Bluetooth part work?

Hello everyone,
I`ve tried to build a BlueSaab 6.1 and I seem to have got close but so far don't have a working one.
So far, I`ve been able to solder it all together and have loaded on the software via the FTDI header.
I`ve held down BOOT0 and reboot, the Arm chip has accepted the software and I`ve read it back out to confirm.
When plugged into the car however, I only get the Red Power light and no other sign of life.
The car (2005 9-5) already had a CD Changer. Do I need to Divorce this first? When cycling through Sources using the Steering Wheel controls, only CD,Radio and Tape show.
I`ve re-flowed the soldering on the Arm chip twice now, but it's never changed it's behaviour.
At present, I don't have a JTAG header soldered on. Is there any other way to debug it?
