Swapping aftermarket HUs, what will I need to do?

Although it's a fine head unit, I've decided my JVC KD-G720 simply isn't for me. The USB interface would be great if I had an ipod, but I have a Zune, so it's aux for me. Anyhow, I've found a unit I want to replace it with, and since I've already got the harness and dash kit from the JVC, I'm wondering if I'll need anything else, or if I'm already set.

Link to the new head unit, just in case. Crutchfield says it fits, but I've been burned before.

Should be a pretty simple swap. As long as when you put in the JVC you used a harness (like you said) rather than splicing, it should be a simple matter of popping the tabs in the cage, pulling out the JVC, unplugging it, plugging in the Kenwood and sliding it into the cage.
