My old RC320 chartplotter died. I have picked up a RC520 as a replacement. However the old gps receiver would not connect to the RC520 as it was a PASSIVE gps receiver. I have purchased an EVERMORA SA 320, and am trying to connect it. I follow the instruction, but I am not getting a fix? Can you help. Could you phone me on 07733111782. Regards Tom
