but this is what id do? delete the recycle an run the antivirus but when the antivirus try to scan de nuvi freeze and the usb connection lost. I try to delete from linux, and the delete of the recycler folder ,the autorun.inf and the boot.exe was succesfull until replug and all appears again. so i think taht the problem is the firmware. I open the firmware in the hex program and see that from region 98 to region FE2 only 00,is that normal?
