If I understood your approach correctly, the only way to achieve this in practice is to have a separate routable map for each activity, and the non-car maps "cheat" by working around Garmin's routing quirks and playing around with the line types, road classes, speed classes, road surface, etc. The GPS is always left in car mode and the right map has to be turned on (and the others off) when changing activities. Is this correct?
Unfortunately yes, for each activity you now need a separate map or stick with the old units / firmware / Mapsource. Maybe hiking and cycling can be combined, but in my part of the world (NL's) cycling and car driving can't. I'm afraid Garmin is aware of this or even care about it.
OK. I don't think it is a complete disaster to have different maps; it's just that this is my first Garmin device and I was a bit surprised about the, let's say, underwhelming routing implementation since those devices seem to be so popular. Do I really need totally different gmapsupp.img files or is it possible to have a generic/shared visible layer but different routing layers on top of it? Can routing information be totally invisible (with/without custom .TYP)? (I have searched the list, but I only found old posts, and I'm not sure if they're totally relevant for new Basecamp/new devices.) I read something about a new NT format which is not reverse-engineered yet. Do you know if new Garmin devices/software respect the access limitations when using this new format (probably impossible to say if nobody understands the format yet)? I was wondering, and this is purely conjecture from my part, if Garmin deliberately made the maps in the "old-style" format less useful in order to reduce competition from free maps such as the ones generated from OSM data.
