On my old TomTom, if I switch from guidance view to map view the scales were about the same, though I could adjust the scale for one to be different. However on my new Go620, you select a destination and when it has found a route, it shows the entire route. When you start driving, it changes to guidance view. But when you click the little directional arrow on the left above the +/- zoom buttons, it changes back to the map view at the entire route scale. I've only tried this for local routes in town and once for a 40 mile trip, and was able to zoom back to a reasonable scale of about a 1/2 mile in map view with a lot of clicks of the + sign. I plan to take a 600 mile drive soon, and clicking a zoom feature a whole lot of times is not appealing. \n\nIs there a setting or an easy way to move to map view and have it scaled at a reasonable value, say a mile ahead for Interstate travel?\nThanks in advance for the advice.
