ok, so my mom wants a 4gb nano for Christmas. no biggie, but i want to go the extra step and get her some sort of car interface. i looked at the USASpec piece, as well as the metra, peripheral, and i think scosche. I'm thinking that the Harmon Kardon Drive + Play is my best bet, plus is nicest/easiest to use. I know that FM Mod kinda sucks, but I don't want her to hate using her iPod in the van because it is not convenient. btw, it's a 2002 Chrysler Town and Country EX. It has the cass/CD with RDS, but I'm not sure about the CDC controls. What do you guys think?
