i have a 3198 cd changer connected to my 2.0 comand hu. The cd changer is not working. When I try to run the d2b wakeup test I get the message " First this test ring must be open" Does anyone know what this means. Please help.

These CD changers all seem to have problems eventually. Are you sure the COMAND is seeing the changer as part of the D2B loop? Make sure the changer's fiberoptic connection is clean and secure. Also did the car come from the factory with this headunit and changer installed? I'm asking because I added a changer after the fact and the dealer had to use the DAS to add the changer to the loop. Before that was done I had a couple of other niggling problems with the electronics.

The only thing I can think of is the car needs to be coded so all of the accessories are recognized. Take it to a dealer or indy who has the DAS software.
