Hi Stefan,

Thanks for the feedback.

It does work with some known limitations.

1 - you need to enter a number or at least make the field blank.
Otherwise, no addresses will be shown.

2 - the incremental search for city names does not work (you mention
this below).

3 - incremental search doesn't work for road names consisting of only
digits

Yes, this is known weirdness.

There has recently been discussed a fix for roundabout direction but
that has not been evaluated yet in mkgmap.

No, the option is still needed and it is called --road-name-pois.

There's known weirdness in that as well because the gps will find exits
in the basemap in preference to exits in the osm map.

Don't know anything about that feature.

Good.
