I have used Garmin 2610s for years now. They work well for me and I've been picking them up used when they show up in the flea market for $100 or less, often with mounts, so I have one on each bike I own. Last week after being gone for 45 days on a canoe trip I went for a ride on my WR250R and the GPS could not find satellites even after 20-30 miles. Also the time and date were off by 15 days and six hours. It had been working fine before I left May 1. In five years of using these units this is the first time one has been unable to acquire the satellites. After I got back from the ride I transferred another 2610 to this bike's mount to test and it worked fine. I tried a reset of the settings and even tried changing the time/date offset and connecting an external antenna, but no luck. Any thoughts on a fix or something to try from you GPS gurus before I pronounce this unit dead?
