Hi Gerd thanks for the first answer. I will do some more tests, especially really using the exact same input data for building land and street map. Up to now, i thought, i used the same, but in my device i have had maps of whole europe and for testing only nordrhein westfalen. So the observation might not be complete correct.

Hi Manfred,
If you created the two maps from exactly the same input files and with the same options reg. routing I assume that this is caused by the differences in the two lines files. Can't say more without knowing the exact input data and options for mkgmap.

Hi all
I've stumbeled about a small routing problem. I do create two types of maps, one is called "myland" with nearly all informations to be found in OSM, the other is called "mystreet" which do mainly show all streets but less information about the surrounding. The two 'lines' files in the appropriate styles are nearly same, except that for the street map all the ways not suitable for automotive driving are not rendered.
My question is, using the same destination in either map, the routing is slightly different in my Garmin 276Cx. For example, routing in the land map uses some grade1 tracks within a forest, the street map does not. But the tracks are to be find in both maps. Anyone an idea, why this is computed differently in the device ?
