By 'complete NZ mapset', do you mean a commercial (and therefor encrypted)
mapset? I'm far from understanding the garmin file formats, but if  
there are non-crypted examples of maps with working street search,  
couldn't there been extracted at least some knowledge?

As an example I have here some OSM maps generated with some unknown  
tool (I asked the developer but got no answer) with working street  
search. So at least some tool out there knows how to do it.

So is someone knows this tool, wouldn't it be possible to generate  
simplistic example maps (like with one or two streets) to study the  
format of the files?

So my question is: are there any known tools that can generate street  
search enabled maps? I obviously only use mkgmap so far. Does  
cgsmapper have this functionality?
