This depends on how Navit determines what town some road belongs to. According to their wiki [1], it uses heuristics based on the town node and town size. (Meerle is in the database in some sense, else its name wouldn't be rendered -- see [2].)

The best way to express that Hoogstraten is in Meerle would seem to be to add the town boundary for Meerle to the database as a boundary=administrative, but it's possible that Navit wouldn't be able to use that information. See also the corresponding OSM FAQ entry [3]. Maybe providing an is_in tag will help, but it's not really realistic to add is_in tags to all streets.

Navit communication channels may be a better place to ask than this mailing list. I'm not sure if Navit developers read here.
