Occasionally after I create a route and load it into my Zumo 550, I want to use the simulated driving feature to ensure accuracy of the route, as measured by what I intended. When in the simulate driving mode, the simulation is sort of in real time. I'd like to speed it up to five or six times the rate it now presents, cuz I don't wanna sit here watching the simulation for hours. Can it be done? If yes, how? And thanks!
