People just want to download a TCX route from websites like Ride with GPS and have turn by turn navigation work flawlessly.

And then it lost all turn by turn navigation.

say because you want to hit a convenience store 2 blocks off your route, then you will lose turn-by-turn capabilities

I would miss the turn and it would lock up to start beeping

For some tcx files, it gives nice turn navigation and for others it just shows a map overlay and pretends it's not navigating me.

Some of this is your personal use context: I want excellent and easy (and intuitive) turn-by-turn navigation for my many multi-day bike tours

What good is a GPS that loses turn-by-turn directions when you're 200km into a ride and you happen to get a little tired or you take a detour

It crashes often, turn by turn navigation fails (works in the beginning, but then stops to work during a tcx course)

Lost all that training data2) turn by turn navigation on a course is spotty at best - 9 times.out of 10 it doesn't tell you to turn, but says "off course" the second you miss the turn

The wise rider will of course continue checking over the shoulder and listening,The downside to Varia Radar is that it overrides Turn-by-turn tour directions

and I lost all turn by turn navigation at that point.
