Final Product Review: Garmin Edge 810 – Time to give up on getting a software update to fix the Garmin 810 crash. It does the basics but crashes when adding maps and live tracking on a real ride. The next tech purchases will be Bluetooth HR, speed, and cadence sensors to use with an old cell phone.
