The TM has Bluetooth® functionality. Bluetooth® allows the user to connect their own mobile phone (Bluetooth® enabled 
only) to the vehicle telephone system. Once connected the user can use the vehicle hands free functions system. The 
Bluetooth® system limits the functions available to those that are present in the Bluetooth® hands free profile. The 
available features include: 
 

Make/receive a call.  
Voice calls using the phones own voice tags (where set up).  

Bluetooth® will not allow the following to be accessed via the IHU: 
 

SMS  
No signal strength indication in the IHU  
Phonebook download to the IHU  
Missed calls  
Last number redial  
Calls list  

Prior to the Bluetooth® equipped phone being used on the vehicle hands free system the phone must be paired to the 
TM. The following describes the pairing process. 
 

Switch Bluetooth "ON" on the handset.  
The user initiates a search for other Bluetooth devices from the handset.  
The TM acknowledges the existence of the Bluetooth® phone.  
Land Rover appears in the handset available device list.  
The user selects Land Rover form the device list and the TM will attempt pairing.  
TM requests a PIN number from the phone.  
The user enters the phone PIN number (this will be supplied by the dealer or will be marked on the side of the TM, 
use the last four characters of the serial number).  
If the PIN number is correct the phone is paired with the TM and its details are stored in the TM EEPROM.  
If the PIN number is correct the phone is paired with the TM and the TM details are stored in the handset.  

Once paired the TM will periodically check for stored Bluetooth® devices (approximately every 20 seconds). As this 
occurs the user will see a connection request on the handset and either accepts or declines the request. This request will 
only happen once per session. 
 
Once the pairing procedure (assigning the mobile phone to the TM) has been completed the mobile handset will 
automatically connect to the vehicle system once they come into range (approximately 10 metres) and the vehicle ignition 
is in position II. The word Bluetooth® displays in the IHU to inform the driver that the phone is connected to the TM. 
 
Each time a paired phone and TM come into range the TM will request connection to the phone. The user can accept or 
decline this request from the handset. 
 
Up to eight Bluetooth® equipped phones can be paired with the TM. Phones van be de-registered/disconnected at any 
time by the user. Only one phone at a time can be used via the vehicle hands free system. If a phone is connected to the 
vehicle via the cradle, this phone will cancel out any Bluetooth® phone operation. 
 
If the TM is replaced each phone that is paired with the original TM will have to be re-paired with the new TM.
