OK, old man ,computer stupid.
I have a place on cedar creek,was trying the art of fine tuning my unit.Some how i managed to screw up
my lake map.now all I get in map is a mini map of half ofthe u.s. I have a navionics card and that was
what iI used to see. Did I manage to turn it off? and undo my STUPID. Any help appreciated.

- and + are Zoom. Use the + to zoom in closer.

You may want to spend some quality time with the manual.

Thank you wayne, I about wore the plus button out.no effect on the scale of the map .Thanks.
