Got a problem with my i Finder Pro, was going across the lake and noticed it was off, turned it back on and kept moving, did it a couple more times. Now it will only light up the back light and beeps when you push the buttons. It has been pushing my buttons sense I upgraded and got the Map Create program that I haven't used yet. After upgradeing thru a download I no longer have the definitions on the maps I had before and while driving on a highway the cursor is off the road?? Any ideas?? I'll try Lowrance Monday but here today. Thanks, Ferdi aka Fred
