Tomtom One speed camera database

Found 26th Dec 2005
I would like to install speed cameras, as Points of Interest, onto a Tomtom One. Can anyone give me simple step-by-step instructions on what to do, please? :?


Not sure if this stuff is compatible with TT1 but worth a try.

pocketgps.co.uk/uks…php to download, otherwise this is taken from pocketgps.co.uk/uks…php


This is intended as an instruction on how to install POIs (especially the PocketGPSWorld camera database) onto all TomTom GO models, i.e. Original, 300, 500, and 700. This also includes the TomTom Rider and One.

If you wish to use the PocketGPSWorld camera database, then you are advised to read the beginner’s guide to the PocketGPSWorld camera database before you continue.

A Points of Interest (POI) database consists of:
a file with extension .OV2 (e.g. pocketgps_uk_gatso_30.ov2)
a companion file with extension .BMP (e.g. pocketgps_uk_gatso_30.bmp)

Back up your SD card before you continue
As a precaution, before you make any changes to your set-up (e.g. add POIs etc) then please ensure that you have a viable backup of your SD card. This is especially important if you have a TomTom Go 300 unit.

Step 1. Download the POI file
Download the POI zip file. Save the file on your computer by selecting “save” when prompted. Save the file in a place where you can easily find it again for step 3 of the installation, e.g. on your Desktop or in My Documents. Unzip the contents.

Step 2. Connect your TomTom GO to your PC
Connect your TomTom GO to your PC using the USB data cable. The USB cable is supplied with your TomTom GO product. Ensure that TomTom GO is powered using the AC adapter.

Your TomTom GO is now visible in "My Computer" as a "Removable Disk".

Step 3. Copy the POI files from your PC
Go to the directory on the local hard drive of your PC where you stored or downloaded the unzipped POI database files (.OV2 and optionally .BMP files)
Select and copy the POI database files.
You must copy the (.OV2 and .BMP) files - do NOT copy the folders.

Step 4. Copy the POI files to your TomTom GO
Go to "My Computer” on your PC;
Go to "Removable Disk";
Then go to the map directory, for example the folder "Great_Britain-Map"; and "paste" the POI files into this folder.

NB If you have a TomTom Go 700, with all of the maps of Western Europe in one place, then you use the "Western_Europe-Map" folder.

The POI files are now successfully copied to this folder. You are ready to use your new POIs on your TomTom GO.

Step 5. Display POIs on your TomTom GO
Finally, to enable POIs in your TomTom GO select them in your POI categories:

Change Preferences | Manage (or Maintain) POI | Enable / Disable POI
Select POI

They now are displayed on your GO screen in both 3D maps and 2D maps.
Even if you do not display POIs on screen, you can now "navigate to" your Poi’s, find POIs near your location, etc.

Step 6. Set up Proximity Alerts (optional)
Change Preferences | Manage (or Maintain) POI | Warn when near POI
Select each POI in turn,
Select the distance for warning
Select the warning sound
Uncheck the "Warn only if POI is on route" box
Repeat until all POIs are set up to warn.

NB. If you check the "Warn only if POI is on route" box, then you will not be warned of POIs that you approach if:
1. The POIs are slightly away from the road.
2. You have no destination and therefore no route planned.

Updating the PocketGPSWorld camera database on your TomTom GO

Sooner or later, the PocketGPSWorld camera database that you currently have loaded on your TomTom GO will be superseded by a later version. We recommend that you always use the latest version.

As always, ensure that you have an up-to-date (and viable) full backup of your TomTom GO’s SD card (or hard drive). Repeat Steps 1 to 4 to copy all of the .OV2 files of the categories and sub-categories of the database to the TomTom GO.

Don’t worry, let the newer versions of the .OV2 files overwrite the existing versions. You do not need to copy the .BMP files of the categories and sub-categories of the database (unless you are adding new categories and sub-categories).

If you have already enabled the categories and sub-categories of the database to display as POIs then the new versions of the .OV2 files will do so as well.

If you have already set up the Proximity Alerts, then these will work with the newer versions of the existing .OV2 files.


The .OV2 file is not in the same directory as the map: see step 4.
The .OV2 file does not contain any POI, or at least no POIs within the borders of the map
You are using a TomTom GO version older than version 4.40.

Some TomTom GO versions (e.g. 5.201) have a reduced maximum limit of (27) POI categories. If you find that your newly added POIs are not shown then move some of the less used POI categories out of the folder and check again.


Unfortunately you can't use .WAV files on a GO. However, if you wish to use spoken alerts (instead of the default beeps) on your TomTom Go then your can use the free PocketGPSWorld voices. The article can be found here. Please read it carefully before you start and ensure that you have a viable backup of your storage card in case anything goes wrong

I have this installed on my TTOne and is very easy to set up.

What is an unzipped file?
What is the AC adaptor? If it's a charger to use with the plug sockets at home, I don't have one. Do I need to get one?
How do I ensure I have a viable backup of the SD card? Do I need to get another blank SD card?
Sorry to sound stupid, but it all seems very difficult to me. :?

No worries,

=Unziped file is once you download the file and open it and to install it

=AC adapter is optional, just make sure the TT is fully chrged or plugged into the PC via the supplied USB cable.

And the backup can be performed via the installation cd from TomTom via the PC and USB cable.

Hope that helps

it's all a piece of pi$$ to do!

you'll need winzip to unzip the download file ([url]www.winzip.com[/url])

as you know the ONE doesn't ship with a PSU, you'll need a DC 5V 2A adapter (the PSP and most PDA's use these) or let it charge up in the car first - assuming you want to connect the ONE to your PC via usb.

If you have a memory card reader for your PC it's a lot easier.

You don't really need to make a backup at all, however it's easy to do. You can use the software cd to do it or just simply slap the card into your mem card reader and copy the entire card to a folder on your pc.

then it's a case of copying the relevant files (.ov2 .bmp) as per the instructions to your Great_Britain-Map folder on the ONE/mem card

I'm too scared to do this incase I mess up the information on the SD card. I've made a backup of the card. Would it work if I got another SD card and put the original information onto that, then tried to add the speed camera data as well. That way, I think I would still have the original intact in case I make a mistake.
If this would work, could you please explain the unzipping thing to me in simple terms. Thank you. :?

dude all you're doing is adding some extra files (pocketgps*.*) into the GB map folder.

you can certainly make a new sd card, just copy the orig to your pc and then back onto a new card, no need to authorize it. As I said, use the cd to do it or use a mem card reader.

unzipping is just uncompressing the zip file. like I said use [url]www.winzip.com[/url]. I can't believe you've never come across an archive file before??

if your using the USB cable i had problems putting it on my Nokia

it doesnt show system files, use a mem card reader to be safe

also there might be hidden files, in XP go to TOOLS>FOLDER OPTIONS>VIEW and make sure the show all files is ticked (and maybes the show Operating system files)

hope this mite help
