4. Cover the exposed wires with several wraps of electrical tape or mastic. Place one wire tie over the electric tape
over the exact location where the wires are 'wrapped' together. Place another wire tie 1” to 2” from the first wire tie,

External GPS Antenna (Optional)
External antennas are generally only necessary if the V4 GPS unit is enclosed in a radio signal interfering area (e.g.
metallic box, under seats, on dashboards with flat windshields, and in cabs or cockpits constructed primarily from
metallic material).
The suggested installation point is the centerline of the vehicle roof, with minimal cable run to prevent wind and car
wash damage. Ensure that there is a clear antenna view of the open sky, and maintain a minimum of 6 inches from any
roo op edge or ledge. See below.
