Karoo 2 not recording GPS or sensors since update 1.2.40.1100.12

    That's interesting Harry. One ride since I updated to that version I had all sensors paired and had turned on turn-by-turn for the first time in weeks. As I rode, the first turn appeared and was announced. The strange thing was the distance traveled had, and continued to, stay at zero even though the unit knew when to announce the turns, the direction of the turn, distance to the turn and the name of the next road.Only a roadside reset and loss of a couple of km of the ride restore it. Un-pairing/re-pairing including Built-in GPS did nothing to fix it.

    It stayed stable for the remainder of 90+km but I did a factory reset when I got home anyway. That seems to be a necessity after firmware updates lately.

    @Harry @Bob: We are extremely sorry to hear about this negative experience on your recent ride. We would like to investigate the issue further. I have created a support ticket requesting some additional details for us to debug the issue. I request you follow up on the ticket.

    I had this after the last update. I went into system and enabled GPS and everything was good again....but I lost the first 4 miles of my ride and many strava "Golds"

    Running 1.251.1117.12, I have the same behavior described by Harry and Bob. Turn by turn route navigation and on screen ride recording works per usual, but my most recent two rides have no recorded route according to the hammerhead dashboard, strava, and the on-device ride recording.

    Another issue that may be related: the first of the two rides had a lot of tight switchbacks and trails close to one another, and my Auto Pause feature was going absolutely haywire. I actually turned auto pause off in order to make any progress (time + distance) at all. I rode the mountain bike in the woods probably 20-30 minutes with less than one minute of actual ride time. Once I disabled auto pause, the ride time statistic continued per usual.

    Hi, I suspect my issue may have been caused by a sensor I was using. It was a Garmin GSC10 speed & cadence sensor. This is an old sensor and has been replaced with a newer model by Garmin. The GSC10 looks like this

    I also had issues with the elevation profile freezing whilst the map, navigation and other sensor metrics updated ok. The elevation wasn't paused which can be done by clicking on it. The elevation would sporadically update every 30 mins or so.

    I changed the sensor to a new Garmin hub mounted speed sensor (as I use it on the turbo). The Karoo has worked ok since. May be coincidence, hopefully not.

    I wonder if Chris's experience may have something to do with what I had -- in my case, my sensors were actually working great under the update that OP cited, but on 1.251.1117 (from 18th November) I had another speed sensor dropout cause an irrecoverable auto-pause (until moving GPS above speed in my sensor list again).

    I had just swapped in a new battery, since the one in my sensor had dropped below 50% so I wanted to rule out any voltage issues or cold weather.  However on a warmer weather ride with the fresh battery, the dropout occurred when climbing slowly out of the saddle on a steep pedestrian ramp over a highway.

    I suppose it may be the low quality of my sensor (a Magene S3+) where at slow speed, dropping a couple data points may trigger an autopause.  The problem is, after I get going again, my Karoo 2 refuses to resume my ride.

    I still don't understand why there can't be a software implementation to check or fall back on the GPS speed to confirm that I'm still moving.  Auto pauses that happen when the GPS speed clearly indicates I'm moving is my #1 frustration with my Karoo 2 and I haven't seen any intention to fix this or any explanation why it's not being fixed.

    Mike, the auto pause not resuming behavior you describe matches the behavior I experienced on my problematic ride the other day, where auto pause was enabled, exception is I am using no external sensors (I am using built in GPS only).

    I did a factory data reset today and went through the setup process again, but on today's mtb ride after the reset, with auto pause enabled, I have no recorded GPS data at all. Ride averaged ~10mph with a handful of slow sections sprinkled in, and the interface did not show the auto pause indicator at all.

    What I wonder is if this update changed some sensitivity thresholds to the point where any functions which observe GPS information no longer see any changes happening. Pure speculation. I nabbed a photo mid ride:

    Hi,
    2 years later, I had the same problem. I tried to deactivate speed sensor, stop the ride and start it again, but without impact. I finallay gave up et start recording the last part using my Garmin watch.


    I finally, triggered my garmin watch  and recorder parially this. but the karoo stays at 0 km et avg speed : 0

    running last release :  Hammerhead Software Build Version 1.413.1603
