Help....please

[BILLY D.]

Baking Soda and water work well. When all the cruddy stuff comes off dry with a Q Tip.

If you can't remove all the corrosion use nail file boards, or sometimes a pencil eraser will shine the metal up.

Also invest in some corrosion inhibitor.

Dats about all I got pardner.

Best wishes, Bill

One other thing, change battery brands. Ya might be able to get a new GPS if ya sue the company that manufactured the batteries, but I doubt it.
