International Classification:

G06F 7/00

US Classification:

701 36

Abstract:

A telematics system for a vehicle includes an infotainment module, a codec module, and a control module. The infotainment module outputs data to a speaker via a first audio data path. The codec module outputs data to the speaker via a second audio data path when a telematics function of the telematics system is triggered. The control module switches from the first audio data path to the second audio data path after the telematics function is triggered. The control module changes a state of a relay of the speaker and a gain of the codec module in a first predetermined order before outputting data to the speaker via the second audio data path.

US Classification:

726 7, 726 8, 726 9

Abstract:

A method for reactivating a telematics device configured to make a data call via a roaming partner of a service provider is disclosed. The service provider has an authentication bypass feature which uses an authentication bypass key common to the telematics device and the service provider to allow the telematics device to make a data call without authentication. The method comprises setting the authentication bypass key on a server of the service provider equal to a previous authentication bypass key, wherein the previous authentication bypass key was used by the authentication bypass feature prior to deactivation of the telematics device. The method includes setting the authentication bypass key on the telematics device equal to the previous authentication bypass key. The method further comprises commencing the data call through the roaming partner by sending the authentication bypass key to the service provider from the telematics device via the roaming partner.
