After a short 44 mi. ride this morning here are my findings:
Grade % = completely useless. Garmin remedied the limit of 6 or 7% but now it is wildly erratic, inaccurate and never stabilizes. The numbers are all over the place. I made several stops after riding different gradients and took notes:
Flat (0%):
+5, -2, 0, +4, +3, -1, +2, 0, -4, +3, -2, 0, +1
3-4% grade:
-1, -3, +9, 0, -4, +5, -2, +7, -3, +6, +4, 0, -2
On a steeper climb, 10-11%:
After around 6-7% it was less erratic and made smaller fluctuations between 8% and 10% which is normal. I don"t know if it ever displayed 11% as I was dividing my attention. ;-)
It's just as bad on descents.
Incident Detection: Garmin has increased the sensitivity WAY too high! From 21-22mph I made a stop and lifted the bike six inches to maneuver around some road construction. The darned alert sounded! Good thing I was able to cancel it before it shot off messages. I have permanently disabled it.
BT Connection (phone): I'm one of the luckly ones who previously had no problems with my (older) phone, Galaxy S5, until today. It always connected right away but not today until about a half mile into the ride.
Autostart LiveTrack: Unable to test (see above)
Recovery time now displays at the end of a ride.
Recording to micro SD: I haven't yet connected my 1030 via USB to actually verify this but today's ride listed in History has an asterick associated with it. I am assuming this identifies the file as being located on the SD card. That said, I did not get the usual "Ride uploaded" message at the end of the ride. Worse, I attempted to upload it directly from the device and received an "upload failed" message. Some minutes later, notifications appeared on my phone, both GC and Strava. Problem may be coincidental, or perhaps not.
I forgot to test the 3D mode on the map. Next time.
