I am a Zumo 550 user and I just bought GPS 620 for my enduro bike. During the years I haven't seen much improvement in the software. I'd like to see following improvements (or tips for workaround):
1. In device's GUI there is the "avoid sandroads" selection. I'd like to see "Favor sandroads", as I mostry ride an Enduro bike.
Maybe it would be easy to do in the sofware, just remap the speed values of roads internally for the routing algorithm, then the "fastest" would actually do the trick?
Is there a method for the end user to do it?
2. Also, "Avoid motorways" is too strict. I wouldn't mind driving let's say 5-10% of the travel distance along a motorway.
3. Third, If I have a route and I'd like to see gas stations, I'm primarily interested on the ones on my route forward. Now the search engine is looking from every direction. Even better if it would give a tip "20 km to next".
4. And if I don't have a route, I don't want my map to rotate on screen.
