Service Overview
Our Radio Frequency Adjustment service updates the audio and infotainment module configuration to match USA radio standards. We read the current regional settings, adjust frequency step values, enable RDS where supported, and correct de-emphasis settings. The radio then receives stations accurately and displays station information correctly.
What the Service Includes
- Full diagnostic readout of the audio and infotainment module
- FM frequency step adjustment to the USA standard of 200 kHz
- AM frequency step adjustment to the USA standard of 10 kHz
- RDS text activation for station name and song display
- De-emphasis correction to the USA standard of 75 microseconds
- Regional preset update and post-adjustment verification
How the Radio Frequency Adjustment Works
The audio module stores regional parameters that control how the radio tunes, displays, and processes signals. These parameters include the FM frequency step, AM frequency step, RDS configuration, and audio de-emphasis setting. When a vehicle arrives from another market or receives an incorrect configuration update, these values no longer match USA broadcasting standards.
LR-Retrofit connects to the vehicle using JLR diagnostic equipment and reads the current radio configuration. We then program the correct USA values into the audio module. The radio immediately scans stations accurately, displays RDS text correctly, and produces proper audio quality. The infotainment screen shows the updated station list and presets without any loss of saved favourites.
JLR Platform Compatibility
We supply Radio Frequency Adjustment for Range Rover, Range Rover Sport, Range Rover Velar, Range Rover Evoque, Discovery, Discovery Sport, Jaguar F-Pace, XF, XE and I-Pace. Most vehicles from 2015 onward with factory infotainment systems qualify. Our team confirms your VIN and current radio configuration before you book the service.
Programming and Verification
LR-Retrofit technicians complete the adjustment at our workshop. We connect to the vehicle, read the existing regional settings, and load the correct USA calibration values. After programming, we clear any stored faults and perform a station scan to verify accurate frequency reception. We also test RDS text display and audio quality to confirm correct de-emphasis.

Frequently Asked Questions
Why does my USA vehicle need a radio frequency adjustment?

Will the adjustment affect my factory warranty?
No. LR-Retrofit uses genuine JLR diagnostic software and follows factory programming procedures. The adjustment preserves original calibration integrity and diagnostic compatibility.
