| Posted by roomtoview not able to uncheck maps in nuvi 255 HI I am having a problem with my nuvi 255 I am unable to uncheck CN MAP when I want to access other maps on sd card. I was able to but not now ?. I have done a reset ,screen calabration updated the software ect ...I know how to manage the maps through mp info screen. My only thinking is that a file has been deleted bfore I ve backed it up The maps I have on the sd card are able to be unchecked,but the CN MAP OVERIDES THEM I am hoping for help here.... thanks :roll: |
