The recommended location for the GPS antenna is based on having a level location and a clear view of the sky. If another location, further from the base, is desired, loosen the connector and pull out additional wire in the base. You must re- wrap and
IMPORTANT! The GPS must be located away from obstructions on roof of vehicle. You must have a clear view of the sky for proper opera- tion.
