Heart rate monitor drops and accuracy GPS

As of 2 weeks, my perfectly fine working heart monitor (Polar HR10 N) keeps dropping after some time during a rate, never coming back, meaning the remainder of the ride is flatlined.

Connecting the monitor works fine at first. No idea why the connection gets dropped.

Also I've noticed that the accuracy of the GPS (and corresponding speed, avg. speed) is pretty bad. Knowing I'm riding 30 km/h and the Karoo keeps telling me I'm only doing 21/22. End of the ride: Karoo tells me the avg. speed was X, but when uploaded to Strava it's suddenly much lower.

And finally, the registered calories burned are way too low compared to some other devices. Sometimes even 2x lower.

Is this a software or hardware related issue? Especially the dropping heart rate connection is a very annoying one.

Hi John: Sorry to hear that you are facing multiple issues on your Karoo during the ride. I can help you with this.

I have created a support ticket requesting for the FIT files of the Activities and serial number of your Karoo for us to investigate the issue. I request you follow-up there.
