I've made a SD card with the newest maps of NORTH AMERICA
, all you have to do is just put the SD card when navigation is OFF and then turn it ON.
All is working great, without and "unlocking", you don't lose your warranty in this way! - because you only edit your SD card, not main memory on the unit!
I can put all of that, on the NET to download.
I expect small fee for my time, try to understand that. Write PM or e-mail [email protected]
