hello my garmin write that it's memory its full when i openit but i didn't do enything before that.
i tried to replace some things inside it but it still have the same problem
any idea?

This is a problem for some Nuvi GPS. You can try and delete some unused files such as the help files in other languages, same with voice files. The EULA files can be deleted as well. If your Nuvi has a SD card slot (and most do) then you can have a map on the main memory of the Nuvi and a second map on the SD card.

Hope this helps
