Land Rover IMC Host Changes: Middle East Region Map Updates Using SX-TOOL

As JLR-certified technicians, we understand that Infotainment Master Controller (IMC) region map updates require precision engineering. When vehicles are relocated to the Middle East, updating the East region map involves more than simple software loading – it requires CCF reconfiguration via specialized tools like SX-TOOL. Without proper DOIP ENET WIFI diagnostics and configuration file editing, technicians face navigation malfunctions and system incompatibilities. This guide details the exact protocol for successful Middle East map transitions on Land Rover IMC systems.

Technical Foundations of IMC Region Map Updates

Core System Components

• IMC (Infotainment Master Controller): The central hub managing navigation, media, and connectivity systems
• East Region Map Data: Specific cartography files for Middle Eastern territories (GCC countries, Levant, Egypt)
• SX-TOOL: JLR’s engineering-level software for advanced module programming
• CCF (Car Configuration File): Database storing vehicle-specific settings and region parameters
• DOIP ENET WIFI: Diagnostics over IP protocol using Ethernet/WiFi interfaces for module communication

Technical Update Requirements

Component	Specification	Purpose
Map Data Version	ME23.1 or newer	Includes updated Saudi road networks and UAE POIs
CCF Region Code	ME_AE / ME_SA	Defines Middle East regional settings
IMC Software Level	L645 or higher	Required for ME23 map compatibility

Step-by-Step Region Map Update Procedure

1. Pre-Update Preparation:
   • Connect DOIP ENET WIFI interface to OBD-II port
   • Verify battery voltage >12.6V with 30A power supply connected
   • Backup original CCF using SX-TOOL
2. CCF Modification:
   • Launch SX-TOOL and authenticate via TOPIx cloud
   • Navigate to CCF Editor module
   • Modify: [NAV] Region = ME_GCC
   • Set: [SYS] Territory = MIDDLE_EAST
   • Adjust: [CLIMATE] Temperature Units = Celsius
3. Map Data Installation:
   • Download ME23.1 map package from JLR repository
   • Transfer to formatted USB 3.0 drive (exFAT, 128GB minimum)
   • Insert USB into vehicle’s media port
   • Initiate update via IMC service menu
4. Post-Update Configuration:
   • Perform IMC hard reset (disconnect battery for 15 minutes)
   • Reinitialize navigation system via SX-TOOL
   • Calibrate GPS antenna

Required Tools & Software

• DOIP ENET WIFI Interface: Mongoose Pro or JLR-approved equivalent
• Stable Power Supply: 30A minimum with voltage monitoring
• SX-TOOL Engineering Software: SX-Tool JLR Engineering
• JLR TOPIx Access: Cloud-based technical information system
• USB 3.0 Media: 128GB minimum capacity, exFAT format

Common Challenges & Solutions

Error	Cause	Solution
“Map Data Incompatible”	CCF region not updated	Verify CCF [NAV] Region = ME_GCC
Update Stalls at 20%	Insufficient power supply	Connect 30A external power supply
GPS Position Offset	Region mask misconfiguration	Recalibrate via SX-TOOL > Navigation > GPS Calibration
Climate Display in °F	Territory settings incomplete	Set [CLIMATE] Temperature Units = Celsius
DOIP Connection Drops	Network interference	Use wired Ethernet connection instead of WiFi

FAQ: IMC Middle East Map Updates

Conclusion: Essential Update Protocol

Successful IMC East region map updates require:

1. Proper hardware: DOIP ENET WIFI interface + stable power
2. Specialized software: SX-TOOL with CCF editing capability
3. Correct sequence: CCF modification BEFORE map installation
4. Territory-specific files: ME23.1+ map packages from TOPIx
5. Post-update calibration: GPS reinitialization

Neglecting CCF modifications or using incorrect tools results in navigation failure and IMC software corruption.
