Overview

This article documents the installation of a Motorola T605 Bluetooth Car Kit in a USA spec 1998 Jaguar XJR. The installation will be

the same or very similar in any Jaguar X308. The first generation XK will be similar but the connector and some of the wiring is

slightly different.

Basic Connections

The factory stereo system in the 1998 through 2002 XJ can be easily adapter for an aftermarket Bluetooth car kit now. Other years and

models are similar. Several have been successfully installed making full use of the mute when a call comes in, the line input to the

factory stereo for the phone audio output, and the factory mic. All the required wiring exists under the center console. Look on the

schematic for connector RT2 (a white 10-pin 2-row connector). The pinout is as follows:

RT2-1 = Purple/Red Audio input from phone to stereo line level negative

RT2-2 = Purple/Pink Audio input from phone to stereo line level positive

RT2-3 = Purple/Orange Ground this wire and the radio will switch from music to the phone audio through the cars speakers. Most car

kits have a wire for this that does ground to mute so you can connect directly to this wire.

RT2-4 = Yellow Factory mic positive lead

RT2-5 = Braid Factory mic negative lead

RT2-6 = Black Ground

RT2-7 = Blue/Yellow ACP network positive.

RT2-8 = Brown/Purple Battery positive at all times fed from fuse #5 (5A) in the RH heelboard fusebox.

RT2-9 = Light Green/Yellow ACP network negative. Note: the ACP network is used for the radio button features for the phone.

RT2-10 = White/Green Key switched power fed from fuse #10 (5A) in the RH heelboard fuse box.

If you look into the face of the 10-pin connector, pin #1 is at the top left and pin #10 is at the bottom right. The pins are numbered

from left to right, top to bottom.

2001 X308 Schematic

The schematic above shows the 2001 X308 cellular phone wiring. The 5 wires going to the radio head unit are at the top right. The

battery and key switch wiring differ slightly from the 1998 schematic which shows these wired through RT2. Below is the 1998

schematic:

Here is the detail of the 2001 schematic showing the circuits between the radio and the cellular phone transceiver:

The mute wire (pin RT2-3) is grounded by the cellular phone transceiver when a call is received and during a call. When this wire is

grounded, the radio will switch the audio input from music to the line level audio input wires (RT2-1 and RT2-2) allowing the phone

to be heard through the stereo speakers. The radio will show “PHONE” across the display while the mute wire is grounded.

Here is the 1998 schematic showing power and grounds:

Here is the mocrophone detail:

The microphone wiring runs from connector RT2 up to the roof console. Remove the roof console by opening the sunglasses holder

and twist the plastic mounting pin 90 degrees. Once removed, you will see connector CA67, a blue 2-terminal connector. Connect the

mic for the car kit here.

Here is the wiring color scheme:

The 2001 X308 had a fixed phone option which was mounted in the trunk (boot). Everything else was the same as the earlier models.
