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 map detail from optional MapSource mapping products.
