I just got my radio module last week (HOORAY!!!) and also ordered the SG1 GM steering wheel to sony control stick interface to install in my 2000 pontiac grand prix. I got everything hooked up, but the controls don't seem to be working properly. The only control I have is track forward which is access using track down, and my volume up which is access using volume down. The play/pause button does seem to work though. Am I doing something wrong? I have a markII and upgraded to fw1.03 when I got the radio module, but don't know if there is something else I need to do to get the sony interface working.
