BMW i3 - ABRP oder doch BMW Navi

Route planning with the BMW i3. This year it's off to Vienna-Bad Gastein again. This time I'm testing the BetterRoutePlanner – or at least trying to – and seeing if it turns the BMW into a "Tesla"... or if I can reach my destination more easily with BMW's own Navigation Pro... this time the trip starts in cold temperatures, so I'll try to warm up the battery at the beginning... well...
