AFAIK house numbers are not coded in mkgmap, so you can't use them. In the devices you will have to enter a fake house number in some searches though.
i see. is a house number feature likely to be added at any time in the near future?
i should add that 1) i think there is one good reason why it's really important, and 2) i am working on a project for which it's an absolute requirement.
it's important because in many cities, you will see streets that are segmented. in Albany, NY, Cortland Street is in four distinct segments, and navigating from one to the next is in 2 cases hard. Cortland is not the only such street in Albany, nor is Albany unique among cities on the east coast of the US. just being able to navigate to the center of one segment with no real help selecting the segment is not useful.
my specific application is providing accurate GPS maps for use by fire departments and companies responding to mutual assistance calls outside of their normal areas of responsibility. this is actually a major problem with dispatch processes in NY, but the GPS maps need house number based routing to be effective.
so here is where i point out that 1) i'm an experienced java developer, and 2) i am between consulting assignments and so have some time. can i be of help?

AFAIK at least two tasks must be solved to make housenumber search work: 1) The format of the housenumber part within the garmin img format must be unscrambled. I think Steve has an idea how it looks like (http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2012q1/013549.html) 2) As Steve pointed out there must be an algorithm that associates housenumbers to nodes in roads. This sounds like a good point where you could help. Do you have some ideas how to realize that? WanMil
