The N2 is just this years (slightly) updated version of the N1, which is a slide out, din-sized unit that is touchscreen nav an controls a variety of P-bus devices. The downside to all the pioneer units is that you must insert the nav disc and remove any music/video media from the slot while using the nav. I believe the unit has a small amount of memory so you can plot a small trip and then reinsert your media disc. The Eclipse is far superior imho, as we sell both. Their units all have 2 slots (one for media and one for nav), they seem to be more up to date as far as the mapping software employed, are much better in sound quality (up to 5V preouts), and are easier to use and setup in general. Eclipse models to look at would be the AVN series including the AVN30D, 5435, and the daddyo 5495 (integrated 30 gig drive for both music storage and nav). Let me know if you need any other info. Keep in mind that you will need to consider interface devices for all the following: on-star, steering wheel controls, rear dvd if equipped, and door/warning chimes. You will not be able to reatin the oem xm, and currently only Sirius works on the Elan bus (but I imagine it is just a matter of time until someone releases an interface or Eclipse updates their firmware).
