Turned on my gps and it shows my position but no map. No city,river,lake info etc.

WHAT HAPPENED??!! Help fishing tomorrow morning with the misses.

Solar Storm? This last flare up is supposed to go until early Friday.

For your sake, let's hope REAL early.

Shouldn't the chart part of the GPS mapping be stored on your unit or the sd card? I would check to make sure the card didn't pop out of the slot or something sily like that. I think (I could be very wrong here) that the solar storm would inhibit the gps giving your location not showing the mapping points in the unit.

Unless of course the unit thinks you are in the middle of a desert somewhere lol.

Hit the menu key, then scroll down to "Map Data....", then click the right arrow key and hit "enter". Take a look at your map source information. Select one of the choices and "ok" your way out. If it's not there, go back in and select another source. Keep doing that until your maps show up again.

What unit is this, and are you trying to read the built-in Lowrance mapping, or are you running an aftermarket mapping card?

If you are still having problems, a soft reset may fix it, but I need to know what unit you have.
