Hi all, Steve just found out that we have a bug in the NOD header which is related to the drive-on-left option: Only if this option is enabled we set one bit in the header which has a big influence on the routing: You have to switch on "avoid toll roads" in MapSource and Basecamp to be able to route on major roads Instead this bit should always be set, no matter what drive-on-xxx option is used. This bug is very old and I noticed that some people use toll roads in their style. So I wonder if anybody relies on the wrong behaviour or why nobody complained until now? Gerd
