Another Edge 305

Today I fixed another Garmin Edge 305, although it’s still a bit strange. This one wouldn’t find any satellites, so I pulled it open to look for broken solder joints and after nothing seemed awry I tried it again and it worked fine. I suspect that it just needed some manner of hard power cycle to get it working again.

What’s also strange is that the down arrow button isn’t working, apparently due to the top and plunger of the tactile switch not being there. When I opened the device they weren’t there and I really can’t tell where they went, as the unit appeared sealed. I can’t help but think that it was dropped, the switch broke, and something happened which caused the GPS to need a hard power cycle. Despite this I couldn’t find the switch parts in the case, either by removing the PCB or tapping/shaking it to dislodge things under the glued in battery.
