Hello. My garmin instict solar have not working barometr. Error 83886. Can someone have known Solutions for This? Regards

I've moved this thread to the Instinct Solar forum (was GC Android).

Possible solution here: Instinct Solar - 11.00 Public Release Candidate - Instinct Solar - Wearables - Garmin Forums

Have a look at the following post and see whether it helps. If not, then I am afraid the only remaining option is contacting the Support:
