I owned the Garmin Edge 800 previous to this and was frequently having problems using the routing

if you look on the map on the 820 while this is happening it graphically shows the correct route on the map

For whatever reason the unit then becomes confused during the ride and tells me to take a random turn not in the route until after about 100 feet it tells me to complete a U-turn and gets back to the correct route

I love the functionality of Garmin cycling devices, particularly planning routes on my PC and transferring them to the device.

I’m toying with returning the Wahoo Bolt (EDIT: I did) and buying the more expensive Edge Explore 1000 (gulp), in the hope that it combines the best of my old 800 (usable touchscreen, good routing, good CPU for fast redraws and a usable map page) with the Bluetooth/integration features of the 820 (Varia radar, incident detection, etc.)
