Alright I think I have the Alpine HU that does the XM radio as well. Its an 07 Elise with the factory Ipod adapter. I have had XM in other cars and would just go to channel 1 to activate it. But in this one I cant get to any XM options from the HU. I found images of the same HU online to make sure it was the one with XM and it looks exactly the same. So what am I doing wrong? Going through the source only takes me through tuner, cd, and ipod.
