the garmin that handles heat best
When hotter weather begins, I switch over to a Garmin that can handle the heat, because if I didn't, there would be problems.
I felt that I didn't give the TTO a fair shake, so I bought the Parker 60R safety razor and gave it a go.
I've used both and no, they're not the same. Not at all.
I live in a hot state, so I have to plan for this stuff early.
My current daily driver is the Garmin DriveSmart 76, and while that works very nicely, I purposely use a Garmin model made from over a decade ago because it's much better equipped to handle hot-hot weather.
Sometimes all it takes to feel your age - good or bad - is to take a trip to the gas station.
