I use the Rand McNally unit, version 0.0

 

The TomTom units don't suck, in fact they are extremely competent. The 710 Unit I run in the truck is a Godsend. It's easy to use, fast and has never let me astray. The original TomTom software you could buy for your PocketPC WAS a waste of time though

 

If going with built in get a d3. Save money off the z1/z2 and get a ipd for music storage. Much easier to load a ipod then the internal drive on a z1/z2. Only draw back of d3 is nav disk has to be the the drive when inputing a route, it can be taken out however while driving the route. If you don't want to spring in for a built in unit get a tomtom. I got a bunch of info on the d3 from the avic forums goto http://www.avic411.com. If you go pioneer be sure to get the bluetooth adapter and ipod cable, both are well worth it.

 

Go w/ an in-dash setup please! You will not regret it. The portables are okay, especially if you use different cars quite often. But the nice big touch screen that is integrated with the dash is really the way to go. My ipod plugs directly in, charges it as well. The kenwood unit is hard drive based so no nav disc and it really seems pretty up to date as far as I know.

 

Z1/2 for sure!

 

I'm doing the Pioneer avicd3 in a couple months. i'm only 17 and can't afford the z1 or z2 but i think pioneer is one of the best head units out there by far IMO

 

I use a Garmin c550 it has mp3 play back, and bluetooth, easy and accurate to use.

 

what head unit did you go with?

 

Pioneer AVIC Z1 or Z2 cant go wrong lots of cool features a little pricey but well worth it thats what we roll with and love it.

I agree, it's not just that I have one, but a Z1/2 is about as good as they get. Sure, the D3 has similar functionality but that whole disk-in-disk-out shuffle is just retarded.
