I have a 2001 with DSP, NAV and 6 CD changer and want to integrate the Roady 2 (Delphi) with it. Is there an adaptor to use the current head to display the XM info? I am currently using the tape adapter and the sound quality is awful. The FM modulater is worthless. I read the threads that deal with the commander units and xm direct units. I appreciate anyone's help. I am new here.
