Does anyone know if their is a new version of the SIR-GM1 that will convert my 07 Tahoe from XM to Sirius? I have searched and searched and haven't come across anything. Guys at Circuit City said there isn't anything out yet. Rather not do the FM Modulation if I can help it.

Good Idea Jasonw75. I will go that way until a seamless solution is found. I was hoping to use the head unit to do all the tuning, favorites, etc.

 

I'm pretty sure GM has an agreement with XM to provide their units in all GM vehicles. Needless to say I don't think GM will ever put too much effort into a Sirius adapter. Someone may do something aftermarket though.
