TomTom 'Could Not Connect to TomTom Services' — Fix

What it means

'Could not connect to TomTom services' — live traffic, speed cameras, weather, or online search not updating — means the device can't reach TomTom's servers.
Either it's tethered to your phone over Bluetooth and that link dropped, the built-in SIM's included data period has run out, the phone's mobile data or app permissions changed, or TomTom's servers are briefly down.
Offline navigation still works — you just lose the live extras.

Affected Models

TomTom GO, GO Discover, GO Supreme with built-in SIM
TomTom GO models that tether to a phone over Bluetooth
TomTom Rider
Older TomTom devices with a fixed-term LIVE / traffic subscription

Common Causes

Bluetooth tether to the phone dropped, or the TomTom MyDrive phone app was closed or logged out
The device's included traffic-SIM data allowance expired (older models had a fixed term)
Phone's mobile data off, out of allowance, or roaming disabled while abroad
MyDrive phone app lost its permissions after a phone OS update
A temporary TomTom server outage
On Wi-Fi-update GO models, no Wi-Fi network in range

How to Fix It

Work out how your device gets data.

Newer GO and Rider models with a built-in SIM connect on their own.
Many models tether to your phone over Bluetooth using the TomTom MyDrive app.
Knowing which one you have tells you where to look first.
For phone-tethered models, check the link.

Bluetooth on, device paired, MyDrive app installed and logged in, and the phone has working mobile data.
Re-pair the device if needed and reopen the app.
If the app's been swiped away in the background, the connection dies with it.
Check the phone's data and permissions.

Mobile data on, allowance not used up, roaming enabled if you're abroad, and the MyDrive app allowed to use mobile data in the background.
Phones quietly revoke background-data permission, which silently kills the live feed.
For built-in-SIM models, check the subscription.

On older devices the included traffic data had a time limit.
Look at your TomTom account for the traffic subscription status and renew it if it's lapsed.
Restart the connection.

Toggle Bluetooth or Wi-Fi off and on, restart the device with a 20-second power-button hold, and give it a minute to reconnect.
If TomTom's servers happen to be down, the services come back on their own shortly — nothing to fix at your end.

Frequently Asked Questions

Does this stop me navigating?

No.
The map and route guidance are stored on the device and work with no connection at all.
What you lose is the live layer — real-time traffic and rerouting, mobile speed-camera alerts, weather, and online search results.
The blue route line and the turn-by-turn directions carry on regardless.
