I had a working SIR-PNR2 unit in my BMW, but when I moved it to my new car, the unit doesn't seem to want to play any music. All the other sources work on the Avic Z2 and I can see the channels and display information on SAT radio, but not sound. Any thoughts? Is the unit bad? I tried a new IP-Bus cable, didn't do the trick. If the unit is bad, I guess I will just switch over to XM, but I wanted to make sure it wasn't something else before I drop another 100 bucks on it.

Thanks!

The IP bus cable is plugged into the wrong port on the tuner, comom issue.

If it was in the wrong port it wouldn't display any information would it?

Yup, I am in idiot, I swear I had checked that. Thanks so much!

This just saved me some frustration. Thanks.
