It has lots of programmable stuff. It locates false alarms by GPS and remembers the locations. It has a button to mark locations, like speed traps, and a GPS icon on the front face. It's quite a bit heavier than the X50, but about the same size. It's completely compatible with my existing hardwire setup. It also tells me my speed during an alert.

 

Do you have an X50 also? I'm curious if sensitivity is at all improved (not that the X50 is bad).

 

I think so. I swapped out an X50 for this.
