I have a 2002 X5 that came without the NAV system. I've checked around and it seems to add one would run about $5000 which is way more than it's worth to me. Now I have my eye on the Pioneer AVIC-N2, which has a ton of great features, including iPod support, XM radio, DVD, etc.

Has anyone tried to install one of these in the X5? Any thoughts?
