What must be used to update my Nuvi 1490 with new maps, i usualy use Garmin-MapSource and Jetmouse to generate and install new maps, but those maps dosnt work with this model. Unlocked maps downloaded from here kan be used and works ok but i want to generate a smaller map to use instead, because the need of space on the nuvi!!

Buy sd card and paste new map on it ... Make garmin folder and put map in
can't see problem?

What part of word you need

@Havehus:
look in Tutorials section for this thread: step by step replacing internal map on nuvi 1xxx, 2xxx and -3xxx
