my 07 hoe doesn't have the factory xm radio installed.. i really want xm and i don't want to use a plug n play. i want to control it thru the bose factory stereo. i checked on it once and was told i had to go back to the dealer for a "tuner" but it was like $300.00 or so. my question is are there any other options for me out there. if so a link would be great. thanks in advance.
