I hate to rain on the parade, but this *doesn't* work for me
(Streetpilot i3).

I think I see that some of the widths of the roads drawn on the map have
got narrower (which is an improvement IMHO) but the recalculate distance
isn't improved. Still around 250m for me.

It must be said that because I don't have a working java development
environment, I used a stock mkgmap and hacked the .img file it created.
I was marginally surprised to see that the .img file has only got a
single "GARMIN TRE" header in it, but it's a fairly small map just
covering about 100km x 50km of my area (South Wales). The whole .img
file is about 1.7Mb.
