they are all pretty good. the only issue I have is that 2k for a glorified gps is WAY too much now days when you can buy a garmin nuvi 1490T for 200 bucks. The 1490T has built in Blue tooth and for 120 bucks it will plug into your cars obd II port and tell you anything from revs to mpgs
Get a double din touch screen that works an Ipod for 600 bucks and call it a day!
