I have a 2007 Prius, Package #2 (standard stereo, no satellite radio). I've read some conflicting info on having an aftermarket stereo installed. These are the things I'd *like* my radio to do: 1. Keep use of steering wheel controls 2. Play and charge iPod 3. Show iPod songs on MFD 4. I also use the Slacker radio app on my iPhone and I'd *love* the use of steering wheel controls while using that, but I'm not sure that's even possible. I'm not sure if going with one of the DICE or VAIS systems is a better option, or just buying a new stereo... Any ideas/suggestions would be very much appreciated!
