Hi folks! Just want to share something which happened this morning on my daily dog walk. I decided to take my old friend,the Magellan 310 out and it came up immediately, which is a lot more than could have been said for the garmin. Ok the magellan did beautifully until about 2/3 way through the walk when we simply lost a signal. No receiver problems at all, it clicked or made that popping sound it does when trying to obtain a signal. This continued for about 600 feet. Then I realized I had better go into the gps options to see if this thing was set on Magellan instead of Garmin. Well, I found that it was set on Magellan by some strange mystical means and so went back into the start gps and bang we hadpoor, 3 satellites and never looked back. I travel this area every day so can not figure this out. The only other time I had ever had such a thing happen was when I used the original gps-talk system on the laptop 3 years ago and that could be as flakey as a pie crust. Well so much for that experience. Interestingly my total journey was 2.02 miles. Oh does anyone know how to translate 600 feet in to tenths of a mile? Thanks in advance. Mary Ellen Earls Ps. Don't throw any complicated formulas at me, please because I have enough trouble adding 2+2 and coming up with the right answer with a calculator. Thanks again. Mary Ellen Earls
