NMEA not responding...What does this mean?

[Gadgetman]

Plugged in my Lowrance global map 2000 and turned it on and the message" NMEA not responding" comes up on the screen. What do I have to do to solve this problem?

If you just hooked up your GPS and it has an external antenna, I'm pretty sure it means the antenna isn't getting power so check your connections.

Im not familiar with the 2000 but on my lcx 18 it was no power to the nmea cord. there 3 wires on mine for the nmea power. a red (+) a black(-) and a sheild (-). I hooked them up and all was well! If yours uses the lowrancenet connectors there needs to be a power source for it also!

If you have a T connector, or any other type connectors, make sure that none of the unused ends are capped with the specific fuse available from lowrance.

The 2000 is an older unit so not network thing going on. I hitched it up the same way I always have, havent monkeyed with any wires at all. depth unit still fires up and works fine just the GPS doesnt respond

Have you checked all associated fuses / in line fuses?

There's a chance you puck has it's own inline fuse, depending on the installation...
