Lowrance X27c

[Explorer1800]

I have a Lowrance X27c and it stops reading my chip. Sometimes after a half hour and sometimes after 3 hours it just beeps and goes to the built in map. Any help appreciated.

I have the same type of problem with my H2O and my quick fix is to take a piece of paper and fold it so that the chip makes better contact.

I hope yours is as easy of a fix and not something more serious

You could try taking a pencil eraser and rubbing / polishing the contacts on the back of the card --- maybe even inside your 27c although I doubt if you can get at them. Make sure you blow away all the eraser dust.

Jim's paper idea is a also a good idea to try.

Jim,

Thanks alot, I tried this on Saturday and it solved the problem. Helped put limits of walleyes in the boat on both Saturday and Sunday.

Hey Dan glad to hear that it was a easy fix. Once you have the chips it is pretty hard to go with out

I have same problem w/ X28C HD, have tried everything. it appears that it is the unit itself getting too warm. only happens on warm to hot sunny days. workarounds are diconnecting the unit from the cables and placing it in a cooler for 10 minutes or removing the drivers windshield on my pro-v to get more air moving past the back of the unit's heat sink.. It never blinks out if the windshield is off, no matter how hot it is
