I have had this unit for a while now and enjoy the many features (ipod,navi,dvd,tv) but would like to take advantage of another feature that i have yet to figure out yet...the unit comes ready for XM sattelite radio but i have sirius sattelite radio and would like to know if there is any way that i can hook-up my sirius to this valor unit??? p.s...sirius and xm merged so I called the company to inquire if they had something for this yet and they were not sure and directed me to google -any help would be appreciated
