<font size="-1">I use a gmapsupp.img generated with a reduced style
derived from the default mkgmap-style . Routing for cars works
fine, if the routes are short. But if I try to plan a long journey
(1000 km). The route calculation gets stuck for some minutes at
lets say 80 percent and finally comes to a result. But the
resulting route is something that looks like a concatenation of
beelines. My assumption is, that Nüvi contains an overview map of
the world (or Europe) that I cannot disable. Could I replace it
using --tdbfile in mkgmap? But the option mentions MapSource, I
tried to avoid MapSource for now.<br>
<br>
Routing works fine, if I disable Motorways (or toll roads), but
the route seems to be somewhat inconvenient.<br>
<br>
Perhaps my questions is a little bit outdated, since there are
good smartphone based apps for navigation. But I love my old
fashioned Nüvi. This leads to the next question: Is there a chance
that there will be TMC information compiled into mkgmap maps
sometimes in the future? As far as I understand, nobody knows
where it is stored inside encrypted proprietary maps.<br>
