I got strange problem with GPS
. While motoring, after an hour or so my GPS
freaks out. The set is: GPS: Evermore SA-920 (rs232), connected to Navicom rt-650 VHF
. After sometime on the motor
it starts to show some bizzare characters in place where long/lat/SOG/COG shoud be. Switching the VHF
off and on, then NO GPS INFORMATION show up. Sometime it starts working for few seconds then freaks out again. It looks like it happens only during motoring, and only after and hour or so since starting the engine
. The GPS cable goes through engine
compartment but slight amount of heat shouldn't affect it at all. Has anyone had similar problem?
