I have a 2007 Cayman S with Bose audio that I absolutely love for driving, but it only has a single CD slot that doesn't even read MP3 and no navigation, parking sensors, backup camera, or way to connect to your phone.

I live about 2 hours from a Porsche dealer, but will driving to an area where I'll be close to one for a couple weeks. While I'm there I was wondering about upgrading the tech in car.

Does anyone have any experience with systems that wouldn't void your warranty and would integrate well with the look of the car? I saw some online that didn't match the color.

The highest priority would be navigation, then phone connectivity and being able to listen to music from other formats.
