Yes, that might help. Do you know if osmand actually uses maxspeed:advisory as the speed when present? But, my point is that for a motorway_link, for routing purposes, it is not reasonable to assume 65 mph as the speed. 30 mph is a far better assumption in terms of causing the chosen routes to be sane. >>The positives are: >> >> - ability to have really up-to-date data via osmlive (vs maps updated >> on the 10th, so with plain osmand your data is from 10 to 40 days >> old, unless you don't bother to update -- still very fresh) > > And further, ability to actually update the data yourself (via editing > OpenStreetMap where you find issues/missing data) and seeing the > changes appear in Osmand. I can do that with my Garmin - I was comparing to using mkgmap. But if the OP meant with the proprietary maps, then absolutely, this is a huge point in osmand's favor. >> - not having to have a second device, assuming you'd have your phone >> anyway.

But yes, other than that, you need power. -- You received this message because you are subscribed to the Google Groups "Osmand" group.
