Does anyone know where I can find the specs for the stock stereo for a 2005 Grand Prix. I'm looking at replacing it with an ALPINE CED102 receiver and want to make sure everything will work correctly. I don't car about ON-STAR and I don't have the Monsoon system in my car. Has anyone put this receiver in their Grand Prix and experienced any problems. I was looking for a great receiver to play and charge my IPOD and this one was recommended. I haven't been around stereos for some time now, but know that ALPINE has always had a great name for receivers in general. Any advice is greatly appreciated.
