Well all you said you wanted was the Ipod connectivity a new head unit and double DIN receiver. So disregarding all the other posts about subs and speakers. Get yourself an Alpine Head Unit no buts. They are teamed up with apple to make the best Ipod Compatible units for not too shabby of a price. I know lots of Units can be Ipod compatible but for the quality and price not much can compare. All you will need is the adapter connections from a local well known audio shop for the Ipod adapter and then I would seriousssllyyy recommend getting a SINGLE DIN receiver. I completely agree with Kia Winters on the fact that it gives you a nice little space to hold things and It doesn't look bad at all.
Anymore questions and I will be glad to help you out.
