Abstract
A telematics device comprises the combination of a cellular telephone and an electronic navigation apparatus. The cellular telephone includes a reference oscillator (122) which is also coupled to the electronic navigation apparatus, thereby reducing the cost of the telematics device by avoiding the need for two reference oscillators and also improving the performance of the device by reducing the time to first fix when the electronic navigation apparatus is switched on as the reference oscillator is controlled to a tighter specification than is normal for a stand-alone electronic navigation apparatus.
