I have a Lawrance LCX28c HD in my boat near saltwater. The GPS has been working until about 3 months ago when it started randon disconnects. Now it hasn't work at all in a month. I have cleaned the pins in the back to no help. Is there a common fault that I can target to fix or should I just replace it?
If I replace it with a HDS-8, can I use the same transducer for depth?
