Not so much as confused as totally useless.

I tried this feature on an out and back, a Course I was following as generated by Garmin Connect. At the turn-around I stopped the course I had been following and then started the “Back to Start - Along Same Route” option. The device almost immediately had me taking roads I had not ridden on the out portion and even as I stayed on the route I had ridden, the device was calling for a U turn. I was not able to get it to re-calculate to the return leg.

And as well, navigation on my 1000 is seemingly in sleepy mode. I haven’t navigated with this unit in a while, but tried a new route out on the eastern part of Long Island on Friday, a Course I created on Garmin Connect. The device seemed to be stuck after every turn it indicated, would take upwards of 45 seconds before realizing I had completed the turn onto the new road as planned before the device would catch up with my current location. This was an issue with a few turns that were within a 1/4 mile of each other and the device was unable to call the turns.

I then deleted all the saved courses I had on the device, figuring a bit of clean out of the memory might help. It didn’t, had the same issue today on the out-and-back. Complete lag of 40-50 seconds after a completed turn and a lot of missed turns as a result. So the Nav functions seems to be screwed.

I will try a factory reset, the unit is about 3 years old. Sucks.
