Re: [mkgmap-dev] max-speed and arbitrary values
I think I can confirm what said here. My nuvi 255 seems to learn the speed I drive on each road (with impact on routing decision next time I drive the same area). Also I confirm that many roads has a max speed info that is shown on the screen while I drive the road. --- Gio 4/6/09, Wolfgang v. Hansen <wvhansen@fom.fgan.de> ha scritto:

At least with my Oregon 300 I doubt it: As I use it all the time with my maps I'm cycling always in the car mode. So far the ETAs are still very wrong. If the GPS would learn the speed they should become more realistic over time.
At least the car navs (StreetPilot, nüvi) do learn your speed profile -- don't know about the outdoor navs though. These are probably the same set of speeds that you can set in MapSource.
In addition, there should also be a slot for the max. speed for each road in the maps. Newer devices (I don't have one of them though) along with current maps tell you when you are driving too fast. This is a feature that had been introduced by Garmin/Navteq quite recently.

I think nuvi 300 doesn't have this behaviour. I have driven many times my road to work and it continues calculating about twice the time it really takes me from home to work (about 50 km trip). Using city navigator for the same route, time calculation is correct. Regards Carlos

That is really strange. What's your firmware version? -Wolfgang
