Why did you buy a second hand since the new one is so cheap?
I got a list of Honda CRV 2007 in dash car GPS

I have bought the second one of this list. The latest version of firmware.
Very amazing!
But to be honest, i like the 7th, it's very expensive, even they gave me a coupon of 20USD. It's till 860USD!
