TomTom One 3rd edition, No maps found.

**EllieBess** · 17th August 2019, 08:46 PM

Been trying to have a bit of a go at updating an old TomTom One 3rd Edition, but have unfortunately lost the back up I made on my PC, so when I have installed a new map, and patched it with "FastActivate" I get the message saying "No maps found".

I know that this is an old unit but I want to experiment on this first so I don't brick my "820 Go Live" unit( again I know its old ).

Is there any way of re-installing a good backup from somewhere else or is the unit kaput???

I hope that there is someone on here who is willing to share their expert knowledge to help a guy who doesn't really understand all of this stuff yet.

Cheers.

7 simple steps to update your device with the latest map
To update your device with the latest map, follow these simple steps:

1) VERY IMPORTANT: Connect your device to your computer via USB. Using Windows Explorer, open your TomTom drive and backup the complete contents of your TomTom.

2) Check your navcore version. You can do this either on the device menu under Version Info, or you can check the navcore version in TomTom Home when the device is connected to your computer, or by opening the ttgo.bif file with notepad.
Try to find Navcore 9.510, which work on most devices, it's always possible to install another

3) Check which map is compatible with your navcore using the latest compatibility, found on most forums

4) Get the map which fits you best and which also fits on your device
Delete the old map folder

5) Extract the map using WinRaR or similar.
Copy across the new map folder into the root of the device.
Make sure when you open the map folder it only contains the map files, not another folder within a folder.

6) Download the latest version of FastActivate from the FastActivate thread:
Extract the file and copy across FastActivate.exe to the TomTom drive (the root of the device).

7) Run FastActivate.exe from the TomTom drive, clicking on the first 3 options in order, waiting for each to complete:
Update meta, patch maps, patch navcore.
