Env: Garmin 830, mountain bike, iphone.
When I first started using this setup, my session map always showed my route in a nice, bright red line. Then it changed and started mimicking the 'flow' colors of green, yellow, and red. This is irritating because the flow green is too similar to the map green, so I find it difficult to pick out my route on the map.
This started happening around the same time that I bought a speed/cadence sensor for the front wheel. I don't know if it's actually related, as I haven't been able to find any documentation on this behavior. In any case, fixing the problem by getting rid of the sensor seems a little extreme.
Can I turn off the flow colors on the map? Or alternatively, can I change them so that good flow is represented by something other than green?
