Not a really a problem...You are connecting a device to your USB connection on your PC. Garmin then enters protected mode. The device appears as a hard drive on your system. It is charging, but you cannot view or navigate on the device while it is connected

We have had the same trouble with one of our DC40 collars, its been doing it pretty much since day1 when we got it but now it wont pick up communication at al. We have changed the battery and updated it as well, The light on the collar stays on, it doesnt flash when its on like its supposed to. Any ideas on ficing the problem?
First, try plugging it to another USB port on your PC, if the same error
appears, try using a different USB cable. If no luck the try it on
another PC If you can get in to the device manager and delete the usb drivers, and
drivers for the hard drive, then reboot the computer and reconnect
again, it should reload the drivers and that may work..
The Nuvi should detect the maps on the SDCARD automatically. A notice appears on the screen to install the maps on your Nuvi. This will take a while to copy the maps from the SDCARD to your unit for installation. After this the maps should be able to function without the SDCARD present.
The Garmin Nuvi needs internal memory for map installation. If there's not much memory left the Map installation might fail. Remaining memory can be checked by connecting the Nuvi to a PC/MAC using an USB cable. It ill appear as an external USB drive. The properties of the USB drive shows remaining memory.
If remaining memory is under 5Gb it might not be enough for MAP install. In this case a master reset to the factory defaults clears memory. This will delete all user data so be sure to store your personal POI's in Mapsource.
A master reset starts by pressing the bottom left corner of the screen for at least 20 seconds while pressing the power button once. A question appears to clear all user data.
Red flashing error indicates corrupt software/firmware. Reconnect tom-tom to computer and bring up software that you installed with device (or take this time to install software). Navigate to "reset to factory defaults" and proceed as the software tells you. After that reapply updates to firmware and/ or maps and disconnect properly from computer. hope this helps
I connected the unit to the car charger instead of the USB charger and then held down the reset for 10-15 seconds, after which the system would show the computer connection on the charger and then boot up when not on the charger.
hi.. when the unit is on try to press and hold the reset button for 10
seconds and then release if this will not work charge the unit for 3 to
4 hours using a wall adapter and if still not work try to check if
there is a latest firmware update for the gps then download it.
I don't know how to fix it but i now a way of getting it back to it's original settings like formatting a computer so only do it if completely necessary. Insert the maps backup cd with your unit attatched to the computer by usb. An option of reinstalling original software will appear, click on this after 10 mins it should be back to how you first got it
I got mine last night and all works fine - even though I had to disconnect it and reconnect it to see the internal memory content (preloaded) on the flash drive of the GPS. Once I saw the maps and other data, the Drag & Drop of MP3's worked as expected (using XP). I set up Active Sync as a guest account. Love the unit so far. Easy to use and fast response.
