Open street map into car navigator

hi,
i would like to know if i can upload a openstreet map into a car navigation unit which supports a SD card slot for updating maps (the unit supports I-GO,Route66,Destinator maps)

Thanx

I have never heard of any possibility to export the OSM data into I-Go, Route 66 or Destinator map formats. Noone knows how those mapformats work so we can’t provide maps in that format. That said, you could add an opensource navigator application to your device (if that’s possible) like the ones listed on this page.
