I have a Alpine CDA-855 reciever and looking to add XM service. My unit has a "Ai Net connection on the rear. I have looked into two Alpine XM recievers to add to my head unit; XMA-T200 RF and a TUA-T020XM. Has anyone added these reciever to there head unit? Then there is the antenna issue, I think a dash style is available because I'm not drilling any holes in my car and not interested in tearing down the head liner. AL.
