Component and head unit recos

nismomo

I've been looking around crutchfield for a head unit and component speakers.

For head i'm looking for Navigation and Pandora link to my iPhone by bluetooth. I found these two and would like to hear your opinion on them or if you'd recommend something better.

For component speakers, I want the least invasive system with either small or built-in crossovers and tweeters that will fit perfectly on the tweeter mount on the dash. I want the interiror to look stock. I found these and would also like to hear your opinion on them or if you'd recommend something better.
