I have recently purchased a 2007 GT3, my first Porsche, and it is very special and I am learning to enjoy it immensly. My car has the CDR24 and while I am happy with the quality of the sound and the OE speakers are just fine, I would like to upgrade to either a system with a hard drive or one that has USB capability. I don't necessarily need nav but if a nav/hard drive system similar to the VW RNS 510 is available for the Porsche I would seriously consider it. Basically I want to run either USB for music or have a hard drive onto which i can download my music. I never listen to radio, and I don't want amps or upgraded speaker systems.
Anyone out there got any suggestions? I would prefer a Porsche unit but would consider aftermarket.

 

From my experience, the Denison unit is what the majority of 997.1 owners use. Here is a link to a board sponsors page that typically has great deals.
