Ok...I'm hooked on XM. It works great in the Hummer Avic D3...I would like to be able to use the XM in other cars etc. with the Roady and cradle. Can I use the cradle and a patch cord (3.5 mm to ISP) in place of the GEX-P920XM??? I assume that this will be an audio only connection and tune with the Roady head. Possible??/ Done by others??
Thanks
PS...when the one year sub expired we lasted only 4 days with "real" radio...LOL
