JLR's 3G Shutdown: How a TCU Upgrade Can Save Your Connected Features
As cellular carriers around the world phase out their 3G networks, owners of many older (typically pre-2018) Jaguar and Land Rover vehicles are discovering their connected features have stopped working. This isn't a fault with your car, but rather technological obsolescence. The good news? There's a solution.
Which JLR Vehicles Are Affected?
If your JLR vehicle was built with a 3G Telematics Control Unit (TCU), it is affected by the 3G sunset. This includes many popular models from approximately 2014-2017, such as the Range Rover Sport, Range Rover, Discovery Sport, Jaguar F-Pace, and XE.
What Features Will Stop Working?
Any feature that relies on the TCU's cellular connection will be disabled. This includes:
- The InControl Remote App (no remote lock/unlock, start, or status checks)
- Live Traffic Information
- Stolen Vehicle Tracking
- In-car Wi-Fi Hotspot
- Online Media and other InControl Apps
Features that do not use cellular data, like Bluetooth phone connection, satellite radio (SiriusXM), and standard GPS navigation, will continue to work.
The Solution: Upgrade to a 4G/LTE TCU
The only way to restore these lost features is to upgrade the telematics hardware in your vehicle. This involves replacing the outdated 3G TCU with a modern 4G/LTE TCU from a later model year.
Is it a direct swap? In many cases, it is a near direct swap. However, the process requires:
- The Correct 4G TCU Part: You need a genuine JLR 4G TCU that is compatible with your vehicle's architecture. [Link to a compatible 4G TCU product]
- Professional Installation: The module needs to be physically replaced, often located behind interior trim or under the headliner.
- Module Programming: The new 4G TCU must be programmed to your car's VIN and its specific feature set using dealer-level diagnostic tools.
Don't lose the features you paid for. An upgrade to a 4G TCU can future-proof your vehicle's connectivity for years to come. Consult with a JLR specialist or our team at SX-Tool to find the right part for your upgrade project.
