In dash Garmin Navigation unit made to connect to Car/Truck AV screen.  (Screen not included)  Connects via RCA video cable.  Used this for 10 years in my Nissan for an OEM navigation experience in an older car.  Works great and will accept new Garmin maps via sd card.  The unit is used and wires have been spliced here and there, but all is in working order.  Last picture shows the navigation screen output on my car screen.  Remote control included to control non touch screens.

Customize your ride with GVN 53, a remote GPS sensor that integrates with your vehicle’s audio/video entertainment system so you can hear turn-by-turn directions through your vehicle's stereo and view detailed street maps on your integrated video display. Similar to GVN 52, GVN 53 takes it up a notch with simultaneous output of RGB and composite video¹ and features a high-sensitivity GPS receiver for improved reception.

Navigate with Your Entertainment System

GVN 53 turns your vehicle's audio/video system into a powerful street navigator. Look up and route directly to specific addresses or points of interest — such as restaurants, hotels, gas stations, retail shops or ATMs — while viewing your exact location on detailed street maps. It even announces the name of exits and streets through your car's speakers so you never have to take your eyes off the road. Map graphics are shown on your system's integrated video display. GVN 53 comes preloaded with detailed City Navigator® NT map data, and its card slot makes it easy to plug in additional maps.
