LAND ROVER DISCOVERY 4 L319 ROSEN REAR SEAT ENTERTAINMENT INTERFACE CONTROL MODULE AP1003 – 2010

Used Rosen Entertainment Systems AP1003 Interface Module, removed from a 2010 Land Rover Discovery 4 L319 fitted with a Rosen rear-seat / headrest entertainment system.

This is an aftermarket Rosen Entertainment Systems component and should not be confused with a factory Land Rover/JLR infotainment ECU.

The AP1003 Interface Module forms part of compatible Rosen in-car entertainment installations and provides the central interface between the system’s power/interface wiring and associated rear entertainment equipment.

System: Rear Seat Entertainment / Headrest Entertainment

Application: Rosen In-Car Entertainment System

Donor Vehicle: Land Rover Discovery 4

COMPATIBILITY

DONOR APPLICATION

Removed from:

2010 LAND ROVER DISCOVERY 4 / DISCOVERY IV L319

This module was fitted to a Discovery 4 equipped with a Rosen rear-seat entertainment system.

The Discovery 4 / LR4 L319 vehicle range covers approximately:

2009/2010–2016

However, AP1003 is not a Land Rover-specific OE module.

It is a Rosen Entertainment Systems component and was used as part of various Rosen rear entertainment installations.

Therefore, compatibility should primarily be determined by:

ROSEN AP1003

rather than by vehicle make/model alone.

ROSEN SYSTEM COMPATIBILITY

The AP1003 Interface Module is officially documented by Rosen as a component of its rear-seat entertainment systems.

It appears in Rosen documentation for systems including:

ROSEN AV7700

and is also documented within earlier Rosen entertainment system installations.

Associated Rosen components can include:

• AP1003 – Interface Module

• AP1008 – Power Harness

• AP1010 – Interface Harness / Extension Harness

• AP1011 – AUX Input Harness

• AP1021 – Interface Harness / associated system component depending on system generation

• AP2020 – Interface Harness, Black with Gray identification

• Rosen headrest monitors

• Integrated DVD monitor units

• Remote control

• Game controller

• Wireless / IR headphones

Exact equipment varies according to the Rosen entertainment system and vehicle installation.

IMPORTANT DISCOVERY 4 INFORMATION

This module was physically removed from a:

2010 Land Rover Discovery 4 L319

Therefore, it is particularly relevant for somebody repairing or restoring a Rosen entertainment system already installed in a Discovery 4.

It should NOT be assumed that every Discovery 4 from 2010–2016 can accept this module.

A standard Discovery 4 without a compatible Rosen entertainment installation will not necessarily have the required:

• Rosen wiring harness

• Rosen monitor connections

• Power harness

• Interface harness

• Headrest screens

• Entertainment system equipment

TECHNICAL INFORMATION

The AP1003 is the interface module used within compatible Rosen rear-seat entertainment systems.

It works together with the Rosen wiring harnesses and entertainment equipment to provide the interface required for operation of the system.

Depending on the particular Rosen installation, the complete system can incorporate:

• Two headrest / seat-back monitors

• Integrated DVD playback

• Independent Monitor A and Monitor B operation

• Audio output

• AUX input

• Wireless / IR headphones

• Remote control

• Game controller

• External audio/video equipment

• Vehicle power connection

ROSEN REAR SEAT ENTERTAINMENT SYSTEM

Rosen systems were designed to provide entertainment for rear-seat passengers using screens integrated into or mounted around the front-seat headrest area.

Depending on the Rosen system version, passengers can have access to:

• DVD playback

• Video playback

• External AUX sources

• Games

• Headphone audio

• Separate screen/channel operation

The AP1003 operates as part of this complete system rather than functioning as a standalone multimedia player.

DUAL SCREEN INFORMATION

Compatible Rosen systems can use two monitors.

These are commonly identified as:

Monitor A

and

Monitor B

The entertainment system can provide separate audio channels for the two monitors, allowing the appropriate headphone channel to correspond with the selected screen.

IMPORTANT – NOT A FACTORY LAND ROVER MODULE

The AP1003 is manufactured by Rosen Entertainment Systems.

It is not a Land Rover OE control module and does not have the same function as factory Discovery 4 components such as:

• Factory audio amplifier

• DAB radio receiver

• Bluetooth module

• USB audio module

• Factory Rear Seat Entertainment ECU

• Touchscreen/navigation module

This distinction is important when identifying the correct replacement component.

COMMON REASONS FOR REPLACEMENT

• Rosen headrest screens not powering up

• Rear entertainment system completely inactive

• Intermittent operation

• One or more entertainment functions unavailable

• Communication/interface fault

• Damaged module

• Damaged electrical connections

• Water or moisture damage

• Previous incorrect installation

• Module removed during vehicle interior work

• Repairing an existing Rosen entertainment installation

• Restoring a previously removed Rosen system

IMPORTANT DIAGNOSTIC INFORMATION

A non-working Rosen entertainment system does not automatically mean the AP1003 module has failed.

Before replacing the module, check:

• System power supply

• Fuses

• Ground connection

• AP1008 power harness

• AP1010 interface harness

• Monitor wiring

• Monitor connectors

• Headrest wiring

• AUX connections

• Rosen monitor units

• Electrical connector condition

Rosen troubleshooting documentation specifically recommends checking system connections when entertainment/audio functions are missing.

WIRING / CONNECTION INFORMATION

The AP1003 should be used with the correct Rosen wiring system.

Associated harnesses documented by Rosen include:

AP1008 – Power Harness

AP1010 – Interface Harness

AP1011 – AUX IN Harness

and additional Rosen interface harnesses depending on system version.

The exact wiring supplied with this used module should be determined from the listing photographs.

Do not assume wiring, monitors, remote controls or other accessories are included unless clearly shown in the photographs.

INSTALLATION

This module is primarily recommended as a replacement for an existing AP1003.

Before installation, compare:

• AP1003 part number

• Module casing

• Electrical sockets

• Connector configuration

• Rosen system type

• Existing wiring harness

• Monitor connections

• Power harness

• Installation configuration

For a vehicle already equipped with a compatible Rosen system, replacement should follow the original wiring arrangement.

If installing a complete Rosen system into a vehicle that did not previously have one, additional wiring, monitors, mounting hardware and related equipment will be required.

PROGRAMMING / CODING

The Rosen AP1003 is an aftermarket entertainment interface module, rather than a factory Land Rover vehicle ECU.

It should therefore not normally require Land Rover/JLR vehicle coding simply because the AP1003 module itself is replaced like-for-like.

However, the complete Rosen system must be correctly wired and configured for the particular installation.

ADDITIONAL VEHICLE APPLICATIONS

The AP1003 should not be advertised as exclusively fitting Discovery 4.

Rosen documentation shows the AP1003 Interface Module being used across multiple Rosen entertainment-system installation packages.

Documented Rosen AV7700 installation variants include vehicle-specific systems for manufacturers/platforms such as:

• Mercedes-Benz

• BMW

• Chrysler / Dodge / Jeep

• Lexus / Toyota applications

• Universal Rosen installations

• Other Rosen-equipped vehicles

This means the AP1003 module itself has considerably wider potential compatibility than Land Rover Discovery 4.

However, vehicle-specific:

• Wiring harnesses

• Mounting hardware

• Headrest/seat trim

• Monitor covers

• Power connections

can differ.

Therefore, buyers using this module outside a Discovery 4 should confirm that AP1003 is the required interface module for their Rosen system.

IMPORTANT COMPATIBILITY NOTE

AP1003 is the key compatibility identifier.

Please do not purchase solely because your vehicle is a Land Rover Discovery 4.

Before ordering, compare:

AP1003

with the original Rosen module.

Also compare:

• Electrical connectors

• Number of connectors

• Wiring harnesses

• Rosen entertainment system model

• Monitor configuration

• Power connections

For replacement purposes, matching AP1003 directly against the original module is the safest method of confirming compatibility.
