I recently bought a 2009 VW Rabbit and opted to go with the basic stereo for now (no satellite, just AM/FM/CD changer/iPod), but at some point I'd like to upgrade the stereo to something that tunes in satellite radio, and maybe one that has GPS navigation too. I've seen some pictures online of VW car stereos that do all this (and have the standard VW 6 CD changer and have the iPod connection too). I like the VW stereos and their feature set, and I'm wondering how easy it would be to have my car stereo upgraded to one of these higher-end VW stereo models? Would a VW dealership be able to order one & install it for me? And what model should I be looking for that has those features? I haven't seen too much info online about VW stereos. Or, is there another brand that might be less expensive/better? I saw a couple of satellite/navigation stereos at Best Buy yesterday, but they seemed to only hold one CD (I like having the in-dash CD changer), and I'm wondering if the factory VW iPod connector wouldn't work with a different brand stereo.
