I will try the hard reset also. I have the 60csx, worked great for a week (I recieved it last Monday NEW) Saturday night I had 10 satellites and accuracy to 9 feet. Usually it would acquire a satellite almost instantly IN my house, now it take about 15 minutes of me driving to work to get it to find some satellites, and the accuracy is at 30-50ft.
I think I may buy the extended warranty for $30....
