JLR Radio Frequency Adjustment — Enable Even FM Frequencies for USA Vehicles

We adjust the radio frequency configuration on your USA-market Jaguar Land Rover vehicle. Vehicles built for the North American market leave the factory tuned to odd FM frequencies only, which means the tuner steps in 200 kHz increments and skips every even frequency. Our service removes that restriction and enables the full FM band with 100 kHz spacing. You receive the configuration adjustment matched to your VIN, along with the technical guidance to apply it correctly. After the adjustment, your radio tunes every available station in your region.

Why Adjust Your JLR Radio Frequency Configuration

North American broadcasters space FM stations at odd decimal frequencies, such as 97.9 and 101.1. European, Asian and many other markets use 100 kHz spacing, which includes even frequencies such as 97.8 and 101.0. When you import a USA-market vehicle into a region that uses even frequencies, the factory tuner skips those stations entirely. The same restriction limits reception when you travel abroad or when you listen to low-power community and campus stations that broadcast on even frequencies.

When we adjust your radio configuration, you gain:

• Full FM band coverage with 100 kHz spacing, including both odd and even frequencies.
• Access to the complete range of stations available in your region.
• Correct tuning behaviour that matches the broadcast standards of your market.
• No hardware replacement, no aftermarket tuner and no visible modification.
• A configuration change that preserves every other infotainment function.
• A VIN-matched adjustment that keeps your vehicle consistent with its As-Built record.

Owners value this adjustment when they import a vehicle, when they move between regions or when they want access to the full FM spectrum. The change also supports correct tuning for RDS (Radio Data System) and alternate frequency functions, because the radio recognises every available broadcast frequency in its region.

Vehicle Compatibility and Coverage

We support USA-market JLR vehicles across the major model lines, including:

• Land Rover Defender (L663), Discovery (L462), Discovery Sport (L550), Range Rover Evoque (L551), Range Rover Velar (L560), Range Rover and Range Rover Sport.
• Jaguar F-Pace (X761), XF (X260), XE (X760), I-Pace (X590), E-Pace (X540) and F-Type.

Our adjustment works on vehicles equipped with InControl Touch, InControl Touch Pro, Touch Pro Duo and Pivi Pro infotainment systems. The correct method depends on your model year and head unit:

• Pre-2017 vehicles: These cars use the SDD diagnostic platform, and we prepare the CCF adjustment for that environment.
• 2017 and later vehicles: These cars use the Pathfinder platform with DoIP communication, and we prepare the adjustment accordingly.
• High-line audio systems: Vehicles fitted with the premium audio package accept the full frequency adjustment most readily, because the tuner hardware supports both spacing standards.

We confirm compatibility during the VIN check and identify the correct adjustment path for your specific vehicle.

How the Adjustment Process Works

We keep the process organised and predictable:

• VIN verification: You send your 17-character VIN. We identify your model, build year, market specification and infotainment head unit.
• CCF preparation: We locate the radio frequency parameters within your Car Configuration File and prepare the correct market setting for your target region.
• Delivery: You receive the adjustment file with clear instructions for your diagnostic platform, whether you use SDD, Pathfinder or a supported JLR engineering tool.
• Application: You connect your diagnostic device to the OBD-II port, read the current CCF, apply the modified parameters and write the file back to the vehicle.
• Verification: You confirm the change by scanning the FM band and checking that even frequencies now tune correctly. You also verify that every other infotainment function continues to operate normally.

Our technical team stays available throughout the process, and we answer questions at any stage.

JLR Technical Specification

The Car Configuration File (CCF) holds the regional settings that define your vehicle’s market specification. The CCF resides primarily in the Body Control Module and broadcasts operational parameters to every network module, including the radio tuner. The radio frequency parameter tells the head unit which frequency spacing to use: 200 kHz for the North American market or 100 kHz for European and most other markets.

The ACM (Audio Control Module) reads that parameter at startup and configures the tuner accordingly. When the parameter specifies North America, the tuner steps through odd frequencies only, which matches the FCC broadcast standard for commercial FM stations. When the parameter specifies Europe or a rest-of-world market, the tuner steps through the full band in 100 kHz increments.

Our adjustment modifies the relevant CCF bytes to set the radio frequency market to the correct value for your region. We write the change against your As-Built record, so the vehicle retains a complete and consistent configuration history. The gateway module then distributes the updated parameters across the network, and the ACM applies the new tuning behaviour the next time the infotainment system initialises.

For vehicles equipped with HD Radio in North America, the adjustment preserves HD Radio functionality while adding even-frequency analogue tuning. For vehicles with DAB in other markets, you can select the correct DAB country and DAB format through the audio settings menu once the radio market setting matches your region.
