I cant update maps on device

Either the firmware and/or map is corrupted. I repair this problem many times by flashing the unit with proprietary firmware that allows the unit to boot directly to mass storage mode, allowing access to the units files via a PC. I replace the damaged files, then reflash the unit with standard factory firmware.

The screen your describe on your Garmin Nuvi is quite normal. It's the PC communication mode of the Nuvi. When disconnected from the PC it will automatically restart.

To update Nuvi software and maps - connect the Garmin to a PC / Mac using an USB cable. Then start your web browser (Internet Explorer / Firefox or similar) and go to MyGarmin.com.

To update the Garmin - MyGarmin.com will check if your webbrowser has been installed with the Garmin update plugin. If not it will say so and will lead you through the procedure to install the Garmin web browser plug-in.

After the web browser plugin is installed it will ask you for your Username and Password at MyGarmin.com. If not registered, then register yourself with the serial number of the Garmin Nuvi.

From here it's possible to update your Garmin Nuvi with new Nuvi software and maps using your username / password at MyGarmin.com

To update your nuvi, all you need to do is to connect your nuvi to an internet connected computer and the updates will show on the lower left of your computers screen, click on it and it will update it with the latest software version and maps.
You can also go to your nuvis website and search for latest updates. Just click on the map link and a list will pop up under the map link, select update maps if it is maps you want to update. It will ask you to choose your device from a list, after choosing your nuvi 255w then it will show you the latest maps for your gps, but you have to install its plug ins first.
That is how to update your gps.

You need to update your Operating softvare. Go to a service or contact me.

if your just trying to update the maps and firmware, use TomTom home...you can download it HERE just select your operating system.

after you install tomtom home you will see the option to update your maps and firmware. plug in your go 700 and wait for it to connect to tomtom home, then select your option.

NO!. THE MAPS CAN ONLY BE DELETED USING THE USB CABLE. GO TO GARMIN WEBSITE YOU MAY NEED TO DOWNLOAD THE USB DRIVERS. THEN TRY THE UPDATE AGAIN. IF THE MAPS ARE ON A CD YOU WILL ALSO NEED THE UNLOCK CODES AND THE UNIT SERIAL NUMBER.

The TomTom 520 and 720 are the same unit. the differance is the maps. The 520 has maps of the US and the 720 has maps of Europe. Download the free clearflash utility from TomTom and run it a couple of times. This should clear up your problem. Sometimes the mapset config in the map gets full and it has to be cleared.

do you have tomtom one installed on tyour computer if not go to the tomtom website install that,hook up gps to computer if it says conect to computer ion the tomtom screen hit yes,then try update device
