SANYO has put a new upgrade for the maps for this specific navigator model. Type in the Sanyo model number and map upgrade in google and you will find it. BUT, and this is a big BUT, the upgrade will cost $75. With that price, you could buy a new upgraded navigator.
Got this off a website
CAUTION - I called SANYO's customer service @ (800) 421-5013 to ask
about map upgrades, getting maps for other countries for the SANYO NVM
-4370. The answer: THERE IS NO CURRENT ABILITY TO UPGRADE EITHER
SOFTWARE OR MAPS!!
