Lowrance H20c Won't turn On

[gtofast1]

Unit won't turn on...tried new batteries. New batteries and power cord. Tried to wiggle button. Anyone else have this problem? or is this a job for Lowrance? Unit is 2 years old. Any help would be great...also took unit to Reeds and they were stumped.. Thank You

I saw a post last week were a H2Oc woould not turn on and he removed the lakemap chip and it worked fine. Apparently the chip went bad. Just thought you may want to try this before sending to lowrance, if you have a lakemap chip that is.

Tried that still didn't turn on. but thanks for the help. Any other thoughts?

Just got unit back today from Lowrance. Put chip in unit and all my waypoints are gone....I guess when the unit crashed it took all my waypoints with it.. Is there some way to store them so I don't have this problem again?

If you get yourself a blank SD or MMC card you can download waypoints from your h20 to the card, then back them up on your computer.

Thanks for the help, I'll go pick one up. Still trying to remember some of the way points. But it's like having a new one to start with.
