My Satellite Radio experience. I love my satellite radio. G35 Coupes manufactured after March 1, approximately will be wired for Satellite Radio but mine wasn't. (these cars will arrive in the USA about now)
My SR uses an FM modulator, with my FM radio tuned to 87.7 and works great. I have Sirius.
You guys will like this. (the ones without navigation) I have the Kenwood SR and was trying to find a place to install the head, without putting it in the cabin. If you open the compartment where nav is suppose to go, the bottom of the door as you open it has a flat area on it. I installed my SR control head on this flat area with two sided tape. (the same that is used for body side molding, very strong) When you open the nav lid there is the SR pointing straight at you. The low profile SR antenna is on the back deck, dead between the back speakers. (inside the car, not outside)
Hope this helps someone.
Take care,
Alan

 

Thanks for the info. Has anyone verified that cars made before March can be wired to use the SAT button? I thought a while back someone had a post with pics and part numbers for the Nissan / Clarion reciever for this.
