Is this what you mean:

Yep, thanks!
The roadtrip file in this directory does not have the index information added. Could it be, that it was generated before the updated gmapi script was in place? (The date on the file is 16-Nov-2009 12:24.)
Cheers.
Hmm, I downloaded it and saw the mdr directory in the file so I assumed it was in place. But I now see from my previous post that I updated the gmapibuilder script later, should have spotted that myself. Thanks for having a look at it though.
I just generated a new map and tested it. The Roadtrip files were correctly generated with the proper index files. I assume then that the previous files were indeed generated before the updated script was in place.
There may, ahem, be other problems with the address search, but not with the gmapi generation script. 
Cheers.
Thanks Clinton for testing!
I’ve made a small upgrade to the toolchain and upped the ‘version’ by one day: A new Splitter version (Thanks Chris Miller!) now makes it possible to do recursive generation of the tiles without breaking the inter-tile routing as was the case for the last ~2 months. If you zoom in on NorthWest Europe you might notice that the tiles do not overlap anymore. If anyone still experiences inter-tile routing: please report. The same OSM data is used for 12-11-09 as was used for 11-11-09.
The next update will use the updated Splitter for America also.
Any New Zealanders here that use these routable maps?
I have the Garmin/Navteq maps on my device for North America and Europe, but as luck would have it, I will be making a trip to New Zealand this spring (autumn in NZ, rather!). As this trip will definitely be a one-off, I am wondering if people have had much luck using these maps for finding places and routing between major points in NZ.
In Canada, the OSM maps are still very much a work in progress and can’t be relied on for routing at this point. Still fun to use and find disconnected nodes to fix, etc. Although I’m not opposed to just buying the Garmin map for NZ, especially if it’ll be necessary, but I thought I’d ask some opinions of the OSM community before dropping $100 on a map that I’ll be using for 6 days.
Any info from New Zealanders or anyone who has used these maps there would be greatly appreciated.
Well you should ofcourse never soly rely on a gps, because batteries can get empty or the thing gets lost or whatever. Preparation and a 20 bucks standard highway map will help you get along quite nicely. This is what I do anyway because getting a general overview of an area from a 4" screen and slow processor is no sinecure.
Just browsing around New Zealand doesn’t give me a feel that coverage is very good, but I could be wrong as New Zealand is way less crowded then Western Europe. Your future contributions for NZ are very welcome ofcourse 
You may wish to check the NZ Open GPS project, which appears to produce a high quality routable map:
Cheers
Just downloaded 63240036.img from your site. That is a China tile. Inspected with wordpad it shows a lot of english text but also a lot of questionmarks ??? ???.
Then I downloaded the data.osm for that area and ‘discovered’ that nearly all 'place’s which names were not in english but in chinese had an extra tag name:zh_py.
This name:zh_py is like int_name and name:en and contains alway english ansi.
Suggestion: you could add this tag to your name tag list.
Yes, I can do that.
Edit: done, just in time for the update.
hi Lambertus. Glad to have found such site discussing about garmin maps.
i have a garmin 255 and wanted to install the map of cyprus. have noticed in my unit that only the major roads are available.
how can i install openstreet maps on my unit?
Select Cyprus on the website map, enter your email address and click the button. The site will confirm your request (or return an error).
If successful, you will receive an email with an URL. Open the URL and discover a few files.
I’m not familiar with the Nuvi 255, but here is some generic information on how to get the map on your device.
Thanks everyone for your quick responses about the New Zealand maps. Some good advice, to be sure.
I always make sure to take a paper map along with me, just in case of a dead/stolen/lost GPS while travelling. Like anything digital, a good backup is always a good idea!
Thanks again!
This weeks update is delayed due to tool problems. I’m reconfiguring to work around it, then do a regular update followed soon (hopefully) with an update using the same data but with the transliterator results from greencaps included.
Edit: the new update is online. Looking at a sample in China it seems that using the name:zh_py tag is working very well! Next update will hopefully contain Russian, Polan, Romanian and maybe some other transliterations using greencaps’s tool as well.
–name-tag-list=name:en,int_name,name:zh_py,name
This is a succes. Just downloaded a tile of China 63240036.img and compared it to that of last week. There are so much less questionmarks.
In osm data of China I see: and GUANGHAN SHI is now in the file. It was not last week.
I have to add that not always name:zh_py contains valid ansi (or is it ascii). But then what does it matter? A questionmark for the one or the other?
Great Job guys. I am continuing to edit my area, and have covered a lot of territory for just myself working on it. Lambertus, I have a question. On your GPS unit, what is your accuracy reading when you are mapping. Mine is 9-14 fee always and was just wondering if this was sufficient.
sphyg: good job, have you become addicted already?
Under normal conditions, placed on my bicycle mount and clear sky view the GPS displays the inaccuracy as 4-6 m. It gets worse in dense built-up areas or heavy tree cover. Keep moving in straight lines as much as possible helps the algorithms to estimate where you are.
9-14m is sufficient enough, especially if you are in unmapped countryside areas. A line that is possibly 10m off is better then no line at all.
It has come to my attention that some map building requests don’t succeed (resulting in only an osm_routable_tiles.zip). This is probably due to an too-complex tile in the Netherlands (there might be other tiles too). I’ve reported this and hope a fix will be available soon.
I think sphyg had a typo (fee) and he, like me, resides in one of those less advanced parts of the planet where they still use “statute” units rather than metric. 9 to 14 feet is pretty good. Sphyg, are you using an external antenna? WAAS?
