Last year in November I got a Garmin etrex Vista HCx to use mainly for recording tracks to upload to OSM. I've been primarily just leaving the device in my car on the dash to record where I drive. My setup involves a car USB adapter and the Garmin friction dash mount. When I stop driving I unplug the car USB adapter and the Garmin shuts down after 30 seconds. When I start off again I plug the car USB adapter again and then power on the Garmin. (My car is a Volkswagen, so the dash power adapter is always on, even when the car is not.)
In the first week of June, the Garmin would no longer turn on. I was able to record my morning commute, and my trip out for lunch, but then for my commute home I could not get the device to turn on. I tried all possible combinations of swapping batteries and removing the memory card, but no luck. After emailing Garmin support, I was able to get an RMA for the device and send it back for a replacement.
Less than 2 weeks after getting the replacement, my replacement device will not turn on (exactly the same problem as before). I'll probably end up sending this one back as well, but this is getting frustrating. It seems that the Garmin etrex Vista HCx is fairly popular in the OSM community. Has anyone had similar problems?
