Yes. I want to format Garmin internal memory on a kenwood dnx9260BT. I want to do this because the navigation constantly reboot during trips. I tried to change the map but with no results. When the device is working, is working fine. But i have to many reboots, i i read on this forum that this problem can be fixed with a reformat with prepusb. All the posts related were for standalone garmin devices witch can be put in pre-boot mode.

Thanks
