Hi,
Actually, on my GPSMap 76Cxs the address search kind-of-works even without using the --road-name-pois option*. I have to enter a house number of some kind for it to work though (even if the destination doesn't actually have a number) and it only works for some addresses, but I haven't tested it fully as it's not a facility I actually need.
*At least, I haven't been enabling the --road-name-pois option when invoking mkgmap and I assume it isn't enabled by default.
Enabling road name POIs does not help the address search function. It's a completely separate function. It was provided as a cheap hack to get some form of road name searching. Arguably, it works better than the address search which, as we know, is less than perfect. Cheers, Mark
