Hello
i bought a new YF Chinese GPS with this spec :
screen size: 5" Resolution : 480X272
OS : win ce 6
RAM : 128 MB
GPS Module : Sirf Atlas 5
Cpu : 600 Mhz
Memory : inside flash 4GB and SD card up to 16GB

it has worked fine until recently, but now (by mistake) i think i deleted some files and because of that my GPS starts loading the welcome screen and doesn't proceed to the menu - it always writes "loading...", but doesn't go further.
i tried to connect it (like i did before...)to my pc via USB, but unfortunately i get the message "USB not recognize".
the GPS loads the files from internal memory and not for SD card.
please help me i don't want to throw it to the garbage

thanks
