The Rino 110 Portable Navigator is a GPS enabled handheld that integrates radio functionality to provide two way communications. It can send communications up to two miles using FRS channels, 5 miles using GMRS channels and can beam your exact location to another Rino user using position reporting. The Rino 110 has standard FRS/GMRS capabilities, so you can talk to friends or family who own conventional FRS/GMRS radios. The Rino 110 has a built-in city point data base with 1 MB of internal memory for additional points of interest data that can be downloaded from a Mapsource points of interest cd rom.
