Hi Bernhard,
I have added city auto fill to your code. Unfortunately I was not able to test it on gps. Problem is that I don't know how to search for roads on my nuvi 360. Maybe this only works with NT cards on the nuvis ? The address / intersections search still asks to spell a US State. I also didn't found any effect in GPSMapEdit. Hints are welcome. I see the same problem with your HW Exit patch.
Thanks for the patch, it didn't really work but was a good starting place. I have just posted a revamped version which, for me, fills the city info as required. Obviously, it needs to be widely tested. As I don't know anything about the Nuvi, I can't help you. Sorry. GPSMapEdit, I think pays no attention to the address data. I have checked with maps produced by cgpsmapper, they don't seem to show it either. The HW exit stuff is sad. I have wasted so many hours on trying to make the OSM exits be shown in preference to the basemap exits that I don't want to look at that code any more! Cheers, Mark
