I allready look for answer in other topic but no luck. How can you upgrade thr maps.
1 In the Nav manuel says abaout a website, you go there there is no 2011 sonata listed.
2 you hit the main button and in system information it say UPGRADE MAPS, you touch the button an start to download somethig, i dont know. Yo have to plug somethig in the usb port to do that otherwise it say usb is off or somethig
3 if somebody is going to tr try number 2 write down the system version of the Maps that appear before you hit the UPGRADE MAPS, and see if it changes.
All of this is in the NAV manual i think 3-51
Go read, try and post your expirience. if this works do we have free updates
