Edge 1040 ASIA , version 17.29 software update is available for download
Updated my 1040 to V17.29 yesterday Grade delay is not improving
17.29 update landed in Japan too. No release notes yet maybe tomorrow?https://www.garmin.co.jp/products/intosports/edge-1040-solar/#updateTab
Don't upgrade to this version. Battery drains terribl.
Not seeing any abnormal battery drain after upgrading. Back from a long ride of 10.5 hours and still got 75% of battery life which more or less matches pre-upgrade figures. This was riding in outside temperature of over 32ºC.
