As most of us are aware of the garmin tabs debacle, I wonder if the rear varia radar can be tethered, as I would hate for it to fall off never to be found again - does anyone know if it can be tethered? Also, is the firmware upgradeable?
If it falls off, you will know about it pretty fast since the head unit (e.g. Edge 1000) displays a huge warning box RADAR DISCONNECTED. So you won't have far to look. With any luck, it will bounce near the curb and not into traffic!
YES, the firmware is upgradable. In fact, firmware 2.20 was just released. Release Notes are:
◦Made improvements to ANT+ connection stability when connecting to Edge 1000.
◦Made improvements to reduce the number of false detections.
◦Added UI improvement to indicate button press using LEDs.
◦Fixed collection of bugs
To upgrade the firmware, plug the Varia into your computer. Start Garmin Express. Add the device to Garmin Express. Perform the upgrade. Unplug the device from your PC. Power-On the device. Now, the lights will turn on from left to right as it loads the new firmware. After that, you are now on the new firmware level. You can plug it back into Garmin Express and hit refresh to ensure that the new firmware was installed.
