Technical Information:
This unit forms part of the original Land Rover multimedia/infotainment system and works together with other factory-installed audio and navigation components.
Functions associated with the system include:
• Factory radio/audio operation
• CD playback
• Satellite navigation integration
• Communication with the factory multimedia display
• Integration with other vehicle infotainment modules
• Communication through the vehicle’s original electrical/network architecture
Exact available functions depend on the specification and optional equipment fitted to the vehicle.
Infotainment System Information:
The Discovery 4 uses a networked infotainment architecture rather than a completely standalone conventional aftermarket-style radio.
The head unit communicates with other components within the vehicle, which can include the display, amplifier, navigation equipment, Bluetooth/telephone equipment and other multimedia modules depending on specification.
Because of this, matching the correct head-unit version is important.
Common Symptoms / Reasons for Replacement:
• Radio not operating correctly
• CD player malfunction
• Navigation system problems
• No audio or intermittent audio
• Infotainment system failing to initialise correctly
• Communication faults within the multimedia system
• Internal electronic failure
• Damaged CD mechanism
• Replacement following water or electrical damage
Important Diagnostic Information:
A completely dead or malfunctioning infotainment system does not automatically mean the head unit itself is faulty.
Before replacement, check:
• Relevant fuses and power supplies
• Wiring and connectors
• Factory amplifier
• Multimedia display
• Fibre-optic/network connections where applicable
• Other infotainment modules
• Diagnostic fault codes
A fault elsewhere in the multimedia network can sometimes produce symptoms that appear to originate from the head unit.
Programming / Coding:
Because this is an electronic infotainment component, vehicle configuration should be considered when installing a used replacement.
Depending on the donor and receiving vehicle specifications, diagnostic configuration or programming may be required for full functionality.
Professional installation and Land Rover-compatible diagnostic equipment are recommended where necessary.
Installation:
Designed to fit into the vehicle’s original factory installation using the appropriate Land Rover wiring and connectors.
Disconnect the vehicle battery correctly before removing or installing electronic infotainment equipment.
Care should be taken not to damage connectors or surrounding dashboard trim.
Important Compatibility Note:
Please compare the following before purchasing:
• Part number BH22-18C815-AB
• Electrical connectors
• Audio system specification
• Navigation specification
• Vehicle model and production year
• Other factory-installed multimedia equipment
Discovery 4 and Range Rover Sport vehicles were available with different infotainment specifications, so do not purchase solely by vehicle year or engine size.
Matching BH22-18C815-AB is the safest method of confirming replacement suitability.
