Hello everybody new to a forum. i have updated maps in my 1490 and now i have no map data available. tried to download again and it says software is up to date. funny thing on my sd card maps show as 2014 when i turn the unit on it says copyright 2015 used to say 2012. i am at a complete loss as what to do. i have two of these units but not willing to hook the other one up to pc. and yes the card is fat32 it's a 2 gig card. any help would be appreciated. does anyone think i should buy a new one instead? thanks in advance.
