Hello!

I have an '07 Chevy HHR and the SIR-GM1 apparently won't work. I heard that the new SIR-GM3A does, but is it available yet? Anyone heard anything about the SIR-GM3A?

Been waiting for one here also. Last I read was supposedly out by the end of the year. But then again, at one point they were claiming they'd be available in the summer. I gave up on our HHR, and use the XM antenna for my Sportster.

thanks for the reply :) i'm thinking of satellite as my holiday gift to me, so you like the sportster?

Yeah, we have one of the older sportster replays and it has been good. Also have a Streamer GTR and a Stiletto S100. Haven't had any problems with any of them. I've seen good reviews on the Sportster 5. One thing is all the newer radios have very weak FM transmitters due to an FCC crackdown, so aux input or direct wiring the FM (FM direct adapter it's called) is the way to go. Hop on over to siriusbackstage.com and you can find tons of info on the different radios, etc.
