I have just picked up a 2006 Chevy Avalanche with Onstar.

I saw on an Onstar forum that you may be able to connect car kits to the audio speakers and onstar microphone. I have a Blackberry 7520 and am trying to decide between the Parrot CK3100 or the Motorola IHF 1000 bluetooth car kit. Do anyone have any recommendations?

I want to make sure I can still use the Onstar. I have talked to the folks at “soundgate” they have a cable to hook up to the Avalanche's stereo and said with onstar you buy 2 Bosch relays and the onstar will still work but they thought I would need to add a second microphone. also not sure Onstar will work beyond the 911 feature. Can anyone give me some advice here? Is there an easier way?

Thanks Dan
