If your tomtom gps is saying no map, the problem simply is that there is a problem on the gps device.
I have three suggestions for you to solve this problem. First, follow
the step-by-step instructions for the "no maps found" situation in this
If this doesn't work, follow the text instructions that I have written
below. And as a final option, you can always call TomTom tech support
at 866-486-6866 and they can help you out.
First of all, connect the device to your computer and close down TomTom
Home software. (make sure it isn't even open in the system tray).
Now, open "my computer" and find the device. It will be labelled as a
storage device (could be drive E:, drive F, etc. depending upon your
computer). Open it up and find where the maps are saved to. Something
like, North America, USA, or something similar relating the place you
live. Once located, delete them manually.
Now, reopen TomTom Home software and go to "tools." Click ''use latest
map guarantee''. It will then download the maps again and install them
onto the device.
Next, disconnect using the option "disconnect device'' from the device menu.
Finally turn on your TomTom if it doesn't turn on automatically, and you should be back in business.
One additional tip: disable your anti-virus software before downloading
& installing the updates. After this is complete, you can just
restart you anti-virus.
