No GPS signal on TomTom PRO devices

Published 05/04/2012 12.35 PM | Updated 12/04/2012 11.30 AM

Recently we discovered that a proportion of TomTom navigation devices do not obtain a GPS position, caused by a bug on a third party chip. The issue could potentially occur on TomTom PRO navigation devices.

A software update fixing the issue is now available for download and installation via MyTomTom.

We recommend to update all PRO devices with the latest software (10.534 or higher) as it includes the fix for the mentioned GPS issue. The update is mandatory whenever the navigation device is used independent from a TomTom LINK 300/310.

To update the software on a PRO device, follow these steps:

Install MyTomTom.

If you haven’t already installed MyTomTom on your computer, read the FAQ: "MyTomTom"
Connect your navigation device to a computer and switch it on.

MyTomTom starts automatically when a compatible TomTom PRO navigation device is connected to your computer and it informs you if there are any available updates for your device.
Download and install the update.

If MyTomTom does not automatically check for updates, click on Check for new items.

A window opens showing the updates available for download.

Click on Start downloading. Do not disconnect your device until it has finished the installation and has restarted.
Reset your navigation device.

Press and hold the On/Off button until you hear the drums sound and the device restarts. This takes up to 30 seconds.

Test your device outdoors.

It is usually not possible to get a GPS position while being indoors. Therefore we advise to take your device outdoors in clear view of the sky. Getting a satellite position for the first time after installing the update could take up to five minutes.

To confirm a successful GPS connection, you can check the GPS status on your device.

Additional tips:

Check if the latest software version (10.534) has been installed on your device. If you do not know how to check the installed software version, click here for instructions.
If software version 10.534 is not on your device, try clearing the cache in MyTomTom and repeating steps 2 and 3. To clear the cache click on the TomTom icon in the lower-right corner of your computer screen to open the MyTomTom support application. Then click Settings, select the Cache tab, click Empty the cache and finally click Save settings.
If you have been unable to get the software update using Internet Explorer, you might want to try another browser, such as Firefox or Chrome.
If you have version 10.534 of the software installed, and still have no GPS signal, repeat steps 4 and 5 above.

Note: Please be informed that there are no known issues for TomTom navigation devices that obtain the GPS position using the TomTom LINK 300/310. Obtaining the GPS position via LINK 300/310 can be easily selected on the navigation device when tapping in the Menu on "WORK" » "Settings" (page 2) » "Use LINK GPS". This should be the default setting anyway.
