You can use Help Me to search for a service centre, make contact by phone and inform the centre about the precise details of your current location.
When you search for a service centre, you are shown a list of nearby locations. Select one of the centres in the list to view their address and phone number and your current location on the map.
To use Help Me to locate a service centre, contact the centre by phone and navigate from your current location to the centre, do the following:
If your iOS device has a phone feature, you can tap the button showing the phone number to dial it immediately. If your iOS device does not have a phone feature, you are shown the number so you can dial using another device.
Once the call is answered, for a description of your current location, open the TomTom app again and tap Help Me. A description of your current location is shown. Tap the description to copy the text. You can then paste the description into a text message or email.
The TomTom app starts guiding you to your destination.
