A method of interfacing a portable wireless transceiver in a telematics system comprising the steps of:
- a) bringing the portable wireless transceiver into a proximity of a first vehicle, wherein the portable wireless transceiver has short range and long range wireless transceiving functions;
- b) automatically switching the portable wireless transceiver from a power-off state to a power-on state in response to a short range wireless signal from the first vehicle;
- and
- c) operating the portable wireless transceiver as a telecommunications device for at least one system within the first vehicle, wherein the portable wireless transceiver is coupled to the first vehicle through a short-range wireless link.
A system for interfacing a portable wireless transceiver in an in-vehicle telematics system comprising:
- a) a portable wireless transceiver having a first short-range transceiver unit and a long-range wireless transceiver unit;
- and
- b) a second short-range transceiver unit coupled to the vehicle telematics system;
- c) a monitor within the portable wireless transceiver capable of recognizing signals from the vehicle telematics system transmitted from the second short range transceiver unit to the first short range transceiver unit;
- and
- d) a power-on circuit within the portable wireless transceiver responsive to the monitor, wherein the portable wireless transceiver switches from a power-off state to a power-on state in response to a short range wireless signal from the vehicle, wherein the portable wireless transceiver operates as a telecommunications device for at least one system within the vehicle, wherein the portable wireless transceiver is coupled to the vehicle through a short-range wireless link.
