Jaguar S-Type Bluetooth Not Working, PHONE NOT FITTED
Each message points to a different fault, and the cheapest is usually the answer. PHONE NOT FITTED on a car that used to pair — I'd look at a fibre-optic plug in the boot; HANDSET IN USE — unplug the module itself; a caller who can't hear you — redo the pairing before touching the microphone. And sometimes the message is simply true: the car is pre-wired, but no module was ever fitted.
How bad is it · Safe to drive
Safe to drive — only hands-free calling is lost
Nothing else is affected. The exception: if radio sound goes at the same time, the fibre-optic audio ring is open — see the first version.
Which one applies to yours depends on your symptoms, your model year and what has already been done to it.
Likely causes, most common first
Read the check cost before the odds: a free check that rules a cause out beats a likely guess that costs money.
A fibre-optic plug in the boot has come apart
The phone module talks to the radio over the fibre-optic audio ring. If one connector on the ring separates, the module drops out and the radio reports it isn't there.
Bluetooth worked, then suddenly PHONE NOT FITTED. Ticking the phone option in the hidden set-up menu doesn't stick. Radio sound may come and go too.
Take off the left boot side panel by the navigation DVD unit and check both halves of each fibre-optic joint are locked together. Keep the ends clean; don't bend the fibre tightly.
Rejoin the connector — everything works again.
The Bluetooth module has locked up
The module keeps its own power and can hang believing a handset is in use. A battery disconnect doesn't always reset it; pulling its own plug does.
HANDSET IN USE. PLEASE REPLACE HANDSET on every start, and no phone menu.
The module is under the centre armrest. Unplug its single connector for about ten minutes, reconnect, then pair again.
Unplug the module, then pair; the phone screen comes back. Switching the phone off and pairing again can also clear the message.
A corrupt pairing — delete it on both sides
After a phone software update, or with several old entries for the car stored, the link sets up half-way: the call connects, but the microphone path or phonebook doesn't.
You hear the caller but they can't hear you, with any phone; or Connection Unsuccessful and the car won't go back into discovery.
Forget every entry for the car on the phone, turn Bluetooth off and on, pair using the car's procedure. Leave the phone in the switched-off car a few minutes so the phonebook finishes loading. On the car side, the telephone booklet gives a keypad command that drops a paired phone and its phonebook — # #3 #*# on a 2007 car.
Forget the car on the phone and pair afresh — it fixes this where wiring, codes and microphone checks find nothing.
A retrofit with wrong pins or the voice module off the ring
Most 2003-on cars are pre-wired, but the connector pin layout doesn't always suit the Bluetooth module, and the voice module must sit on the fibre-optic ring for microphone audio. The phone module must be the Bluetooth type — the one for the earlier Motorola handset won't work.
Just had modules added: the phone function is missing, or calls work only on the phone's own speaker.
Compare the phone module part number with the kit; count the pins in the connector under the armrest (the kit needs eight). Check the voice module has fibre leads in and out. The Bluetooth interface module follows the VIN: C2S3689 up to N51372, C2S3835 from N51373 to N58845, C2S43926 from N58846 — check a current catalogue for supersession.
Re-pin the connectors so Bluetooth is offered, and make up a fibre lead to put the voice module into the ring.
The car was never fitted with Bluetooth
"Bluetooth preparation" means wiring only. Factory modules arrived part-way through the 2005 model year, earlier cars aren't all eligible for the dealer kit, and some modules have been removed.
PHONE NOT FITTED or NO PHONE since the day you got the car, and no pairing screen. A roof microphone proves nothing — every car got the wiring. An early car's built-in phone is the old analogue Motorola handset system: the cradle is wired for that handset only, and no other phone will work with it.
Look under the centre armrest and in the left boot side for the modules. NO PHONE relates to the phone module and armrest handset; NO BT PHONE means Bluetooth is there but nothing is paired.
Nothing to repair: a retrofit, or an adapter on the audio input. Check your build date is eligible for the factory kit. A retrofit needs the phone modules, a roof microphone and a head unit reprogrammed with the dealer tool — about $1,000 at a dealer; an aftermarket hands-free kit is about $200.
An early module that forgets itself
The first factory modules had teething problems: firmware on some phones, no phonebook transfer, and the occasional start where the module isn't found.
About one start in ten says PHONE NOT FITTED, and cycling the ignition brings it back. Or with one particular phone: the caller can't hear you, or the phone's Bluetooth crashes, unless it is set up just so.
Try a second phone of another make — some pair and work without trouble. Ask a dealer whether a later phone module version applies to your car.
Worth trying: a later module version can mostly settle it, though phonebook download may still not work. Meanwhile, dialling from the phone's own keypad rather than the car's controls is worth trying.
A failed roof microphone
The headlining microphone is a small, cheap part and can fail on its own.
The other party can't hear you, and re-pairing changed nothing.
Only after deleting and redoing the pairing: try a second phone, then replace the microphone.
Worth trying once pairing is ruled out: a new microphone.

The order to check them in
The point of the order is money: each step either rules a cause out or makes the next one worth doing. Green is free, amber costs a little, red is the one to arrive at last.
Read the exact message
PHONE NOT FITTED on a car that used to pair, HANDSET IN USE, and a caller who can't hear you lead to different causes.
freeDelete and pair again
Forget the car on the phone, clear old entries, pair from scratch. Touch-screen and non-touch-screen cars use different key sequences — check the handbook.
freeUnplug the module under the armrest
Ten minutes off its own connector. A battery disconnect is not the same test.
freeCheck the fibre joints in the left boot side
Especially if radio sound drops out as well.
freeCheck the fuses
On the 2007 layout: F29 10 A in the rear box (telephone, navigation), and in the passenger junction box F29 5 A (telephone transceiver, reversing aid) and F27 10 A (radio, display, voice control). If the navigation works, the rear one is fine; if the parking sensors are dead too, look at the 5 A one first.

If there's none, it's a retrofit or an audio-input adapter — not a repair.

The highlighted position is the one the procedure talks about. Pulling a fuse is a stop-gap, never a repair: check what the circuit feeds before you pull it.
