Address search in OSM

Alright Fellas: Downloaded and installed open street maps to my Garmin Montana 650 (Love IT). Snooped around map, all seems well. I can select a point of interest and unit shows turn by turn navigation just fine. But when I try and do an address search, it will find country/city/county just fine, but no actual house numbers. Street names all appear? I’ll guess I need another download or am I missing something basic here?

Thank you!

Housenumbers are not yet supported by OSM-Garmin Maps. Enter “1” as housenumber and he will
find the street.
