http://www.gpspassion.com/forumsen/t...OPIC_ID=123610 and other threads on it on this site,will probably answer anything you need to know. I have the Nuvi 765, smaller screen than 1490 but graphics much the same, i must say the quality and routing of the unit is top class but i feel as many others do that the lack of detail on the guiding map is terrible, i dont even get route no,s, very few street names no poi's, if Igo or any of the others could route as well as my garmin i would use it as a $500 paperweight.Such a shame their graphics designers havent got a clue,maybe should spend some time with other units. IMHO.
