+de_cache_man Posted September 21, 2005 Share Posted September 21, 2005 I'm having a problem with my Garmin eTrex Vista C. I use it almost exclusively for road biking. I ride my bike on paved roads and I use the GPS to measure speed, distance, elapsed time, elevation, etc. It's been an invaluable tool in my training program. I mount the GPSr to my handlebars with the Garmin handlebar mount. It's sturdy and I've never been worried about hundreds of dollars' worth of GPS crashing to the ground. The problem I have been seeing is that when there is vibration (such as a newly chip-sealed road or a cattle guard in the road), the GPSr powers down. I send an email to Garmin tech support and they gave me an RMA number. I returned the unit to Garmin and they repaired it and sent it back to me. They said that the problem was due to a "loose keypad" and that they had replaced the keypad. The day after the GPSr was returned to me, I went out for a ride and about 30 miles into the ride, the unit shut down again. I thought it was a fluke, but the next day, I rode on the same piece of road and the GPSr kept shutting down. The vibrations from that particular piece of road kept shutting the unit down. Different roads (smoother road surfaces) didn't seem to bother it. Larger bumps (like from railroad tracks or road damage that I saw too late to miss) didn't bother it. I went across a cattleguard and it shut right down. Apparently specific frequencies of vibration kill the unit. I emailed Garmin tech support again and they said that the batteries were probably coming loose inside the unit and that a foam spacer between the batteries and the battery cover would fix the problem. I gave it a shot. I put folded paper between the batteries and the battery cover. It was so tight I could barely get the battery cover back on. A couple of miles later, I hit the same stretch of road, and the unit shut right down. I've replied to Garmin tech support again. It's frustrating though. I have already paid to ship the stupid thing back once, and I'm pretty sure they're going to ask me to ship it back again. Has anyone else with a Garmin eTrex GPSr had such "bad vibrations?" Any ideas on how to fix this without sending it back to Garmin again? I'm not at all excited about paying to ship it back to Kansas again, because I'm not at all convinced of their ability to fix the problem. Quote Link to comment
