Just installed the XM Radio unit GEX- P920XM, activated the account and have no sound coming from the unit. All other parts of the radio work perfectly. Get all the info from XM on the unit but no sound, Is their something I did wrong in the installation, or something to check? Dont know if it is the original unit or the xm unit.

Plug the IP-BUS cable into the right port.
