Was out on the lake and decided to run up the river. GPS was working just fine following old trails and making new ones. Stopped and fished a couple hours and got ready to head back. Pulled up map and everything looked great for a minute then everything started to look funny. I was following a trail back and it stared showing me going slightly to right. Came up to and island and it showed me going over land and I am pretty sure I was still in the river. Got back to the main lake and the direction was wrong and was showing me going to the right maybe 100 yards or so off from where I was. I run the same path every time and it was off.Is there something I can do to get it back to normal?
Thanks

Do you have an Elite Ti first generation or the new Elite Ti2 second generation? Have you been out on the water since this happened, if so did GPS work properly?
