I have just tested a German map using mapsource and can route from W to E across a tile boundary from a place called Zedwitz to Trogen (a few Km) - it's crossing the boundary using a residential street.
Also, the reverse route works as well.
If I switch to the basemap in mapsource it just draws a straight line between the end points.
Do your problems also occur in mapsource or just on the etrex?
Hi Mark, thanks for your support. I have no mapsource running here but testing all on the etrex venture. I use a map of bavaria (some weeks old), downloaded from geofabrik, splitted with Splitter into four tiles automatically. I'm using the latest R942 without modifications. Inter-tile routing has never worked for me, but I thought this is the case elsewhere too, so not mentioned to the mailing list. Intra-tile routing works as expected, even if it shows me sometimes suboptimal routes, but I think this is caused by the osm data. Later I will reboot my system to windows, then I will test with mapsource.
