I improperly disconnected my tomtom

Newer maps are not readable by older device software. Please upgrade your TomTom application to the latest version.

1. Make sure that you have the latest version of TomTom HOME installed.
   • If TomTom HOME is already installed click on Help > Check for TomTom HOME Update.
   • If you do not have TomTom HOME installed, you can download the program fromwww.tomtom.com/home.
2. Connect your device to your computer.
3. Open TomTom HOME.
4. If updates are not offered automatically, click on Update my device.
5. Download all available updates, restart your device and then reconnect your device to the computer.
6. When the updates have finished installing use Device > Disconnect Device.
7. Repeat steps 4 through 6 until the update window shows 'No Items Available'.

Now that you are up to date with your application, check to see if the device still displays the NoMaps Found error under normal operation.

I found this article online, and it may work for you:

"Ok this has worked on at least four tomtom one’s
And one xl’s that i have tried,
First of all connect your tomtom to your computer.
making sure your online,Go to log on.
if you’ve not created an account create one now.
If you’ve had to create an account restart tomtom home.


You should have the tomtom home screen in front of you,
Now even if tomtom home is showing you logged in, ignore
this click your email adderss in the top right hand side of the screen
and log in again and click continue.
Then click Device/disconnect device.
Now your tomtom will update itself and your maps will be restored"

I had the same problem before on a TomTom GO 730. The free internal memory was too small to hold the updated map so installation failed (the download to PC was OK, the message is misleading).
It's a TomTom software bug to not check on the available free memory properly before the update process is started.
My TomTom device required a new software install from scratch. Remove any excess MP3 or unused voices before you retry the update.

No Maps Found usually means the Application on your internal memory is not the latest one, or the map did not download correctly.
Make sure when you select internal memory when updating your device on home, that you update the application as well.
V8351 should be the latest application for your device.

I would shut it off and turn it on. If it persits, just hit the master reset in the back. But what you may want to do is update the maps on tom.tom.com

You probably have a directory on your Storage Card called \Storage Card\My Documents\Map_Name

copy the Map_Name folder to the root of your Storage Card

so you have \Storage Card\Map_Name

restart TomTom and it should pick up the map back. if this didnt work then probably the card directory where the map is stored may corrupt or unreadable try reinstalling the map
at least this has worked in many tomtom one’s
And one xl’s that i have tried,
First of all connect your tomtom to your computer.
making sure your online,Go to log on.
if you’ve not created an account create one now.
If you’ve had to create an account restart tomtom home.

You should have the tomtom home screen in front of you,
Now even if tomtom home is showing you logged in, ignore
this click your email adderss in the top right hand side of the screen
and log in again and click continue.
Then click Device/disconnect device.
Now your tomtom will update itself and your maps will be restored
please let me Know if this has worked for you.hope this helps pls apprecite by rating as fixyaa thanks and Godbless

TomTom makes it really easy to update maps for any one of their devices. You can get the latest Tele Atlas maps from TomTom by heading over to their Map Store. Pick your device, pick your map, and download. While they aren't free, they're extremely accurate and affordable

my tom tom 510 would start, i have charge the tomtom with green light on, but tomtom is not coming up

The problem is caused by a version mismatch between the Application version and the Map Version. They must both be the same. For example, if the TomTom has not had the application updated, but you updated the maps, the TomTom will not know how to read the file.

Make sure that if you are trying to use a version 815 map, that you are using a version 8.XXX application too. I had to upload two application version changes before I could read the new USA maps.

this problem just happened to me. i'd just bought my new tomtom one and tested it on the journey home. all was well and i was really impressed. that was until I got it home and went to update it to get the latest maps for my area. I installed all the software as instructed by the on screen prompts and downloaded the latest updates. i then went to turn the device on, and was greeted by a message stating ''no maps found!''

after almost two hours of complete frustration, i then tried probably the easiest solution anyone could think of:

First of all, connect the device to your computer and close down tom tom home. (making 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 (mine was drive G). Open it up and find where the maps are saved to. Something like, UK and Ireland, or something similar relating the place you live. Once located, delete them manually.

Now, reopen tomtom home 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 tom tom if it doesn't automatically, and you should be back in business. This worked for me, after trying numerous way more complicated solutions I found in various forums.

Hope it works for you too!
