Software 21.17 for explore 2

Yeah, I did the same thing with the maps from https://www.openfietsmap.nl/downloads/europe. The typ files for all their maps are already posted there, you just need JaVaWa TYPchanger.

Apparently Garmin broke all the sensor connections in 21.17. Can't get any type of sensor to connect over Bluetooth or ant+ now. I would avoid downloading this update...

Same problem for me. It is simply ridiculous that it has not been fixed yet

Connection with hrm lost mid ride.....

I am also constantly loosing my HRM ANT+ Connection - if it finds it at all (mostly needs a restart to discover the sensor in the first place). Had no problems before 21.16 

I had the first problems with sensors after 21.16. At the beginning, everything works fine, all sensors connect within seconds, the problem comes, when I stop and turn off the sceen. When I turn it back on to continue my ride, all of the sensors are lost. In 21.16 a screen turn off and on again solved the problem. But now with 21.17 no matter what I do, I could not get my sensors (HRM, power, radar, speed) to connect back to my edge. It is really frustrating

This is exactly my experience, too. No problems before 2.16 - there restarting worked. Now it is broken beyond any workaround…

I will probably stop using the device until this is fixes. In the current state it has no value for me. 

Still not fixed. Appalling service from Garmin
