I actually own the second one you listed (and am selling it actually to replace with an in-dash nav unit, PM me if you are interested or would like to see it in action) and whole-heartedly recommend it. I actually bought it in the Summer to replace the previous version (which I actually also still have in my garage) as the new version adds Pandora. If you have an iPhone, it is a no brainer. The features it has and its abilities are unbelieable. This unit was developed in conjunction with Apple for flawless integration. The iPod navigation is superb. The Pandora feature (I love Pandora, most of my music listening is on Pandora) will be impossible to live without once you have it. The only drawback I have found with this unit is its inability to play CDs.

I have to ask though, are you still using CD's? If you have an iPod, rip them all on there and ditch the changer altogether. Regardless, feel free to ask any more questions you may have.
