I have a 2006 I like it.
If there is any way you can swing a 2007, I'd look into it.
My main thing is the gen 5 Navi has a much better screen. Plus you add the possibility of adding audio accessories via aux input.
My gen 4 Navi screen looks kind of blocky compared to the newer. almost a standard def vs high def comparison.

Just some thoughts.
