The NX720 and 820 have a built in GPS receiver, but not the antenna. There is a jack on the back of the radio where you need to install a suitable GPS antenna. Kenwood sells the KRA-40G GPS antenna, which is a magnetic mount designed to go on the dashboard. . Once you have that, the radio needs to be programmed to know what to do with the GPS signal. It's intended for AVL (automatic vehicle location) where it would send out your coordinates on a specific interval, or when you key up the radio, press a pre-programmed button, etc. There isn't an output on the radio that will allow you to plug in a readout, but there is a GPS Position display function that can be programmed into the menus. It would scroll through the latitude, longitude and altitude.
All this needs to be enabled in programming, and if the radio was not installed with the GPS antenna, it's likely it wasn't done. You'd need KPG-141DN and the correct programming cable, KPG-36um, I believe.
How do you like the radio? Those only started shipping back in October. I haven't seen one in person yet.
