Telecommunication System
Introduction
New Range Rover has the option to be supplied with a built in hands free telephone system. Both the Multi-Function
Display (MFD) and the Multi Information Display (MID) are capable of supporting telephone operation. The system is
based around a portable GSM phone which utilises a standard SIM card.
The following describes key points regarding the telephone system fitted to the new Range Rover.
l
The telephone system is only compatible with GSM 900
l
Only one handset can be registered to one vehicle at any one time. Handsets need to be de-registered before a
replacement handset can be registered to a vehicle
l
New SIM card holders can be purchased through the handbook ordering process
l
Only Land Rover approved SIM card holders should be used. Tests indicate that non approved SIM card holders
can release the SIM card into the reader. Removal of the SIM card from the reader is extremely difficult and could
cause damage to the reader
l
The telephone ECU does not support the use of the * and # keys. This means that GPRS and pay as you go type
services are not supported
l
The telephone system does not support 5v SIM cards. Normally the service provider will change the SIM card
for a 3v version. There is no way of identifying the SIM card voltage from the card
l
The use of dual SIM cards is only supported by some service providers usually at an extra cost.
