Genuine Land Rover Discovery 4 L319 DAB Digital Radio Receiver Module – AH42-19C032-AE / LR019261 – 2010
Genuine Land Rover used DAB digital radio receiver / Digital Audio Broadcasting module, suitable for selected Land Rover Discovery 4 L319 models equipped with the factory DAB audio system.
This electronic module forms part of the vehicle’s factory infotainment and audio system and is responsible for receiving and processing digital DAB radio broadcasts before integrating the audio and station information with the vehicle’s factory entertainment system.

Donor Application: 2010 Land Rover Discovery 4 L319
Manufacturer: Land Rover / JLR
Condition: Used Genuine Land Rover Part
COMPATIBILITY
Land Rover Discovery 4 – L319
Directly confirmed application:
• Discovery 4 L319 – 2010
• Discovery 4 TDV6 HSE application confirmed
• 3.0 TDV6 – 306DT application confirmed
• 5-door SUV
• Automatic transmission application confirmed
• Factory DAB-equipped vehicles
A documented AH42-19C032-AE module was removed from a 2010 Discovery 4 TDV6 HSE with the 306DT engine and ZF 6HP28 automatic gearbox.
The module is also listed specifically for:
Land Rover Discovery 4 L319 – approximately 2009-2014
where the corresponding factory DAB/audio system is installed.
ADDITIONAL LAND ROVER / RANGE ROVER APPLICATIONS
The same AH42-19C032-AE module is also documented on selected:
Range Rover Sport L320
• Approximately 2009-2013
• Factory DAB-equipped vehicles
Range Rover L322
• Approximately 2010-2013
• Factory DAB-equipped vehicles
Therefore, AH42-19C032-AE is not exclusive to the Discovery 4.
However, infotainment-system specification and model year are particularly important, so the existing module number should always be matched before purchase.
TECHNICAL INFORMATION
The AH42-19C032-AE / LR019261 module is a dedicated digital radio receiver used within the JLR factory multimedia system.
Its primary functions include:
• Receiving DAB digital radio broadcasts
• Processing the incoming digital radio signal
• Communicating with the factory infotainment system
• Supplying digital-radio audio to the vehicle’s audio system
• Providing station information to the vehicle display
• Integrating DAB operation with the factory radio controls
• Working with steering-wheel audio controls where fitted
• Communicating with other multimedia modules within the vehicle
The DAB receiver is a separate electronic module and should not be confused with the dashboard radio/head unit, amplifier or navigation module.
DAB DIGITAL RADIO SYSTEM INFORMATION
DAB stands for:
Digital Audio Broadcasting
Unlike traditional analogue FM/AM reception, DAB uses digitally transmitted radio signals.
The factory Land Rover system can involve several separate components, including:
• DAB Receiver Module – AH42-19C032-AE
• DAB aerial / antenna system
• Aerial amplifier components
• Factory audio/head unit
• Central infotainment display
• Audio amplifier depending on specification
• Steering-wheel controls
• Multimedia communication network
• Associated wiring and connectors
A failure elsewhere in the system can therefore cause symptoms that appear similar to a failed DAB module.
VEHICLE NETWORK / MOST INFORMATION
The Discovery 4 infotainment system uses a network of interconnected multimedia modules.
The DAB receiver forms part of this multimedia architecture, and contemporary Discovery/LR4 technical discussions specifically reference the DAB module within the MOST system/module sequence.
This is important when diagnosing a complete infotainment-system failure rather than simply poor DAB reception.
COMMON SYMPTOMS OF A FAULTY DAB MODULE
Replacement may be required due to:
• DAB radio not working
• No digital radio reception
• DAB option unavailable
• DAB stations disappearing
• Radio unable to find digital stations
• Intermittent DAB operation
• No sound when DAB is selected
• Infotainment communication faults
• Module not communicating with the vehicle
• Internal electronic failure
• Water/moisture damage
• Damaged electrical or network connections
A replacement AH42-19C032-AE has been documented by Discovery 4 owners as restoring failed DAB operation.
IMPORTANT DIAGNOSTIC INFORMATION
No DAB reception does not automatically mean the receiver module has failed.
Before replacing the module, also inspect:
• DAB aerial / antenna
• Aerial amplifier
• Antenna connections
• Module electrical connector
• Power and ground supply
• Multimedia/network connections
• Wiring loom
• Relevant fuses
• Infotainment fault codes
• Other modules within the audio system
If the DAB system has poor reception rather than complete failure, the aerial and aerial amplifier system should be checked carefully.
IMPORTANT MODEL-YEAR INFORMATION
JLR changed the infotainment architecture and DAB hardware during Discovery 4 production.
Later vehicles can use different DAB receiver modules, and later-generation modules should not automatically be assumed compatible with an early 2010 vehicle simply because the connectors or casing appear similar.
For a 2010 Discovery 4, matching:
AH42-19C032-AE
and/or:
LR019261
provides the strongest basis for correct replacement.
PART NUMBER INFORMATION
Primary engineering number:
AH42-19C032-AE
Alternative formatting:
AH4219C032AE
Land Rover OE/service reference:
LR019261
These numbers are directly cross-referenced on documented Discovery 4 DAB receiver modules.
INSTALLATION
The replacement module should be installed using the correct Land Rover workshop procedure.
During installation:
• Disconnect the battery where required by JLR procedure
• Inspect all connectors before fitting
• Check wiring for corrosion or damage
• Inspect the aerial connections
• Carefully handle multimedia/network connections
• Install the module securely
• Reconnect the vehicle correctly
• Test DAB station reception
• Check the complete infotainment system for correct operation
• Scan for stored communication faults where necessary
PROGRAMMING / CODING
Because this is an electronic infotainment/network module, do not assume every used replacement will be universally plug-and-play across all Discovery 4 model years and specifications.
A like-for-like AH42-19C032-AE / LR019261 replacement offers the best compatibility.
Depending on vehicle specification and replacement-module configuration, diagnostic configuration may be required.
Programming/Coding: Vehicle/specification dependent
Diagnostic Check Recommended: Yes
Where necessary, suitable JLR-compatible diagnostic equipment should be used to check module communication and vehicle configuration.
IMPORTANT COMPATIBILITY NOTE
Before ordering, please compare:
AH42-19C032-AE
AH4219C032AE
LR019261
Also check:
• Vehicle model and year
• Factory DAB specification
• Existing module engineering number
• Electrical connectors
• Multimedia/network connections
• Aerial connections
• Infotainment system generation
• Module casing and mounting points
• Listing photographs
Do not rely solely on “Discovery 4” when ordering.
Different infotainment and DAB modules were fitted during L319 production, particularly as the multimedia system evolved through later model years.
For a 2010 Discovery 4, matching AH42-19C032-AE / LR019261 directly with the original module is strongly recommended.
CONDITION
