So I'm looking at upgrading my car stereo to accomodate my iPhone 3GS. Ideally I'm looking for a stereo that will integrate my phone and music into my car speakers. So I stopped by Best buy to see what my options were and this seemed to be the best for cost:
If you like GOOD sound and you have an iPhone (not iPod) then please read some background stuff I have observed at

'Look for Quantifying Sound quality'
I think there are a number of equally good systems, but I definately think that the power/cable arrangements going to the iPhone may make a subjective difference between a 320kbps track sounding like it was sampled at 128.
I don't think you'll have the problem with new systems, but it happened that I have an 18month old Alpine model - and to cut a long story short, if you use a 18months old car stereo that was fitted up with iPod cable you get no power to the iPhone and the sound loses hifi and becomes ordinary.

All the best.
