Granted, it's not an in-dash unit, & the screen is samll, but my new Gsrmin 2610 is pretty cool.
It's a GPS nav system that sits on the dash or windshield mounts. The audio directions are pretty good & the re-routing works great if you decide to get off-route.
At about $735, it's about a thousand bucks less than the DVD system that MIGHT come, & works fine.
