Well yesterday went without a hitch!
My GPS didn't freeze!
I took out all the pocket query's that I wasn't using for this outing, four in total. I always update through Garmin Express before loading my caches. I double checked the SD card and clip and everything was in place and secure. When I turned the unit on this time, the display was different. So I reset it back to what I was familiar with. I had approximately 650 caches loaded for the area we were going to placed in the Garmin/GPX file as usual.
I feel I hadn't done anything different other than removing pocket query's that I didn't need. My hope is that if I do want to go to more than just one area I can load more than just one pocket query.
Thankyou all for all your help and input......I was a happy cacher yesterday
