It's running software version 5.70 (1517997). I've been wearing the 245 (non-music), but it is constantly rebooting, so I went to my trusty 645 for a long run. No reboots, but it simply froze up and nothing worked to get it going again. I ended up holding the power button until it reset, but ALL data from the run was lost--even the step count.
I'm livid about this and strongly considering switching to the Apple Watch.
Garmin, is anything being done about the issues with your software? The 245 is virtually unusable as a running device, since one never knows when it may reboot.
