2022 Land Rover Range Rover US to European Map Conversion
Technical Process for Map Region Conversion
Core Technologies Explained
- MAP Conversion: Modifying navigation region coding in multiple modules
- JLR CCF: Central repository for all vehicle configuration data
- sx-tool: Specialized software for low-level module programming
- JET Master: JLR’s engineering platform for advanced coding operations
Hypothetical Conversion Process
- Connect DOIP VCI with battery maintainer (30A minimum)
- Launch JET Master authenticated via TOPIx Cloud
- Access “Navigation System” module via engineering menu
- Modify CCF parameters:
Region_Identifier = EUMap_Data_Version = European_2023.3
- Use sx-tool for firmware reprogramming of HMI module
- Perform region-specific map data upload via Ethernet
- Execute module reset and navigation calibration drive
Required Tool Suite
- JLR DOIP VCI (Mongoose Pro or equivalent)
- Stabilized 30A power supply with voltage monitoring
- JET Master software with valid license
- JLR TOPIx Cloud Dealer access
- European map data package (JLR part #LR084568)
Common Technical Challenges
| Error Code | Solution |
|---|---|
| U1A00-87 (Configuration Invalid) | Verify CCF checksums post-modification |
| D900-DD (Map Data Mismatch) | Reinstall region-specific map package |
| sx-tool connection failure | Check Ethernet connection stability |
Critical Tool: SX-Tool JLR Engineering Suite
For 2020+ models, the SX-Tool JLR Engineering Software provides:
- Direct ASAM-ODX programming capability
- Firmware flashing for infotainment modules
- Checksum validation for all programming operations
Frequently Asked Questions
Can I convert maps without JET Master access?
No – JET Master authentication through TOPIx Cloud is required for navigation region modifications to ensure compliance with JLR security protocols.
Why does my navigation show incorrect speed limits after conversion?
Indicates incomplete map data installation – verify all region-specific packages are loaded and perform post-conversion calibration drive.
Technical Imperatives
- CCF modification must be performed in both navigation and instrument cluster modules
- Always use stabilized power during programming operations
- sx-tool is required for firmware-level modifications
- Post-conversion calibration drives are mandatory for GPS synchronization
