It's seriously hard to differentiate the route versus the normal road while cycling - check out my screen shot -
Imagine trying to discern that magenta route amongst the similar color road while the bike is on the move - it's 1000x clearer here in this screenshot than when out on the bike in bright/dark lighting and you're trying to avoid getting killed by inattentive drivers. Can't garmin choose a more distinctive color (hint hint : bright green)......is tat too much to ask for a $450 technology product?
