Garmin 500 bought for my hubby who WANTS someone to steal it and the endless complaining makes my head hurt (the thing can easily take 5 miles to find satellites while saying "working" the whole time - um, dear Garmin NOT working would be more appropriate message).
The Edge 500 picks up satellites better when you're not moving.
Mine was ready when I was if I turned it on and put it on a window sill while I got dressed, or I turned it on before I inflated my tires.
