Radio Frequency Adjustment (For USA Vehicles)

Overview

USA-market Jaguar and Land Rover vehicles leave the factory with a restricted FM tuning range. The infotainment system locks onto odd-numbered frequencies exclusively — for example, 97.9 MHz and 98.1 MHz remain accessible, while 97.8 MHz and 98.0 MHz do not. This limitation stems from the North American FM broadcast allocation standard, which historically spaced stations at 200 kHz intervals.

Our Radio Frequency Adjustment service removes this restriction entirely. After activation, your JLR infotainment system tunes across the complete FM spectrum at 100 kHz resolution, matching the capability of European and rest-of-world specification vehicles. You gain access to every FM station in your broadcast area — odd and even frequencies alike.

How the JLR Radio Frequency Architecture Works

JLR vehicles manage radio tuning parameters through the Car Configuration File (CCF) — the master electronic blueprint stored primarily in the Body Control Module (BCM). The CCF broadcasts operational parameters to all network modules across the vehicle’s CAN bus architecture. The Remote Function Actuator (RFA) module processes RF communication for keyless entry, remote start, and related functions, while the infotainment head unit (IMC or PIVI PRO) applies the regional radio tuning profile defined within the CCF.

For USA-market vehicles, the CCF encodes a “USA” market parameter that instructs the tuner to scan at 200 kHz intervals. Our adjustment modifies this specific parameter to a rest-of-world (ROW) or European market profile, enabling the 100 kHz resolution required for even-frequency reception.

What Changes After the Adjustment

• Complete FM band access: Tune to every FM station, including even frequencies such as 89.2, 91.8, and 104.4 MHz
• Correct regional map alignment: Navigation data matches the selected market configuration
• Miles to kilometres conversion: Instrument cluster units adapt to the configured region
• Side marker configuration: Exterior lighting parameters align with market requirements
• Language and market settings: Infotainment language and market preferences update automatically

These changes persist through ignition cycles and require no ongoing intervention. The system stores the updated CCF permanently, and all modules read the revised parameters at every startup.

Compatibility

This adjustment supports most Jaguar and Land Rover models from 2017 to 2025+ equipped with IMC or PIVI PRO infotainment systems. Supported platforms include Range Rover, Range Rover Sport, Velar, Evoque, Discovery, Discovery Sport, Defender, Jaguar F-Pace, E-Pace, I-Pace, XE, XF, and F-Type.

Installation Process

Our certified technicians perform the adjustment remotely through JLR-approved diagnostic pathways. The process follows these steps:

1. Provide your Vehicle Identification Number (VIN) for verification
2. Confirm your order through secure payment
3. Install remote support software and share connection credentials
4. Switch the ignition ON and connect an ENET adapter to the OBD-II port
5. Our technician applies the CCF modification through JLR engineering tools
6. Verify full FM tuning range and market parameter alignment

The activation typically completes within 30–60 minutes. You drive away with a fully unlocked FM tuner and correctly configured market parameters.
