The manual map update did not resolve the elevation inaccuracy issue. The issue is "less bad", so the update seems to have done something, but elevation is still way off. I rode a 36-mile route today that should have had about 150 ft. of elevation and the Elemnt Bolt showed total elevation at 906 ft. That's not as bad as the pre-update elevation for the same route, which was 1,299. . but stll not acceptable. I'll be on the phone again tomorrow with Wahoo tech support.
