I had 840, 1030, 1040 and now 1050. I am pretty a faithful client. After 1 year and some motnhs:
1 - battery level showing completely crazy: if I plug stays the same. sometimes hows the eject, sometimes not. When plugged hows 38%, when unplugg it (probably) correct and shows 80% (exmaples). when i save battery, it shows less time than when i turn off save battery mode
2 - it does not connect at all with Mac. I have 2011, 2018 and 2022 iMacs. All updated, so different Os. No recognize, different cabbles, trying through commdn (I am good in tech), nothing.
3 - when conected to garmin express,only sometimes it recorgnize (green sign) but cant update. Errors all the time in updating. thanks god I can send courses through my iphone.
