This afternoon at about 1:15 PM my 60CX failed to get a satellite lock.I removed and replaced the batteries several times to no avail.I also turned the unit on and off several times.I was getting 2 satellites sometimes three but no lock.I then enabled WAAS and 51 came right up with a full bar.After about 45 minutes I gave up and stuck the unit in my shirt pocket.I checked it about 1/2 later and I had 10 satellites and all was working.What could have caused this?Slipshod
