The issue I have with the Nav system (that I don't have in either of my cars) is that the software is kind of low end. I have the same software in a PDA version and I have the same gripes with it. Of course it only ran my company a couple hundred bucks and if I want to use it in another car, I just take it with me. I haven't heard anyone mention it but the Navteq software I have in the PDA also has an almanac (sunrise, sunset, moon phase etc) and also gives satellite data and elevation. I have the entire eastern U.S. on a 1 gig SD card that is a piece of cake to update.

My biggest gripe is that you have to buy the Nav to get the more advanced hybrid gauges. They have to unbundle that!

JMO of course.
