I biked with my Forerunner 405 and with oregon 400T same ride. total up elevation gain as shows up in the MB data is 3,500m (from the oregon) and on the GC (from the 405) is 1,500m . of course the 1,500m is the right data...
how should I fix it and get the right data from the oregon (I cannot upload from the oregon to GC..)
