Radio Frequency Adjustment for USA Vehicles — JLR OEM Market Configuration
Radio Frequency Adjustment aligns your Jaguar or Land Rover tuner, keyless entry, and tyre pressure monitoring hardware to United States market specifications. This OEM service rewrites the market and region parameters inside your vehicle’s Car Configuration File (CCF), so every radio band, station spacing, and wireless frequency operates exactly as JLR intended for North American roads.

Overview: Genuine JLR Market Frequency Coding
JLR builds vehicles for dozens of markets, and each market follows its own broadcast and wireless regulations. North American tuners use FM 87.5 to 107.9 MHz with 200 kHz station spacing, AM 530 to 1710 kHz with 10 kHz spacing, and RBDS data services. European and other export markets operate on 50 kHz FM offsets, 9 kHz AM spacing, and DAB/DAB+ digital bands.
When a vehicle enters the United States from another market, or when a module replacement installs a non-US configuration, the tuner region parameter no longer matches local broadcast standards. You then experience skipped stations, offset frequency stepping, missing RBDS text, and non-functional HD Radio. Keyless entry and TPMS behaviour can also fall outside the 315 MHz band that US regulations expect.
This service rewrites the market code, tuner region, and wireless frequency parameters inside your CCF. We then reconfigure the Audio Control Module (ACM), infotainment head unit, Radio Frequency Receiver (RFR), and Body Control Module (BCM) so they recognise the new market values. Your vehicle finally delivers complete US band coverage, correct station spacing, and compliant wireless operation.
You receive a dealer-compliant configuration service that keeps your vehicle fully legal under FCC Part 15 requirements while preserving every existing entertainment and connectivity function.

Why Choose Radio Frequency Adjustment?
You receive every available US station. The tuner sweeps the full domestic band with correct 200 kHz and 10 kHz stepping, so no frequency falls outside your reach.
You gain complete data services. RBDS station names, programme type tags, and traffic announcements display correctly. HD Radio activates wherever your head unit carries the hardware.
You restore reliable keyless entry. Your remote operates on the 315 MHz band that US vehicles and local infrastructure expect, delivering consistent locking and unlocking range.
You maintain full legal compliance. The adjusted configuration matches FCC Part 15 requirements for unlicensed radio operation, protecting you during inspections and resale.
You preserve your vehicle’s factory integrity. This service writes only OEM market parameters through targeted CCF edits. It never introduces third-party firmware, and your vehicle retains complete diagnostic compatibility with dealer tooling.
Vehicle Compatibility
This service suits Jaguar and Land Rover vehicles imported to the United States, vehicles fitted with replacement tuner or BCM modules, and any model whose CCF carries a non-US market code. Supported platforms include:
- Defender (L663) — 2020 onwards
- Range Rover (L405, L460), Range Rover Sport (L494, L461)
- Range Rover Velar (L560), Evoque (L538, L551)
- Discovery (L462), Discovery Sport (L550)
- Jaguar XE, XF, XJ, F-PACE, E-PACE, F-Type, I-PACE
Your vehicle requires a compatible infotainment head unit and a functional OBD-II port. Some head units carry market-locked tuner hardware, so we always run a VIN decode first and confirm feasibility before you commit to the service.
What the Adjustment Service Includes
- Pre-service diagnostics: We read your current market code, tuner region values, and module software levels, then confirm US configuration availability.
- Configuration backup: We archive your original CCF so we can reverse the change at any future point.
- Market parameter rewrite: We update the market code and tuner region in the CCF, then reconfigure the ACM, RFR, and BCM to accept the new values.
- Band validation: We sweep FM, AM, and available digital services, verify RBDS display, and confirm keyless entry and TPMS operation.
- Post-service scan: We clear all DTCs, confirm zero fault codes, and hand over a written record of the configuration change.
We complete the adjustment remotely through a secure OBD connection or at our workshop. You provide your VIN, and we confirm compatibility before we begin.
