Hi Carlos,
Some time ago I read somewhere Address search in nuvi only works with nt maps. Your patch (v1) had no effect on my nuvi 300: it still asks for a State, but no one is listed.
Well, I think the patch is in its early days. Don't give up hope!
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!
Well, I think you have improved routing performance quite a lot. Previous to your patch I only received "keep right" or just nothing for highway exits and now it says "leave right" which is much more convenient. I have City Navigator disabled in my nuvi and I can see exits on screen. So I think you didn't waste your time.
Thanks, in that respect it's worth having. Perhaps, I shall commit it even though the exit search doesn't work 100%. Cheers, Mark
