This is 'sold' as a combo. The radar and the nav need separate power cables so unless you have 2 handy power sockets you can only use one at a time. So the cables will be all over the cabin of your car. The battery life without on the nav is 5 or 10 mins max. The radar detector makes a nice beep when you plug it in, but doesn't actually detect anything. I drove past 3 police cars on the highway (and had I set to highway mode) and nothing. It just sits on the dash. The nav is pretty good, but takes a while to load when first booted up. It only works when charged due to short battery life. The user manual lays out additonal features like an MP3 and other goodies, but they don't work.

The nav on this unit is really good. The screen is super sharp, but the radar is poor, lot of false alarms and limited range. All in all I would buy another one if this one gets taken away. I use it in a big rig and sometimes they get grumpy about the radar thing. Good unit for the price!
