My Raymarine C-80 Multfuntion Display and Raystar RS125 GPS are generating recuring lost postion alarms about every 10 minutes. The system loses its satalite reception and then after about 5 mintues comes back with a HDOP value of 1.0. Then a few miuntes later generates a lost positon alarm. I've have replced the battery in the receiver then replaced the receiver with a used one. Same issue. Tried to do a firmware update on the C-80 but the system will not read the128Mb CF Flash card for doing a backup or loading latest firmware update. Now the system does not read the chart card. It going from bad to worse. I looking for a reputiable Raymarine repair center that has board level capabilities. Are there any recommendations out there?
