Audio device security system
First Claim
1. An audio device for installation in a motor vehicle including an electronic security system responsive to an electronic security code for operating said vehicle, said audio device comprising:
- detection means to detect a connection between said audio device and said vehicle;
inhibition means to inhibit at least partly the operation of said audio device after an interruption of said connection;
communication means for communicating data between said audio device and said electronic security system;
verification means for verifying data communicated through said communication means in response to said electronic security code;
automatic reset means to uninhibit operation of said audio device following an interruption of said connection if said data are communicated and verified; and
manual reset means to uninhibit operation of said audio device following an interruption of said connection if said data are not communicated or not verified but a predetermined code stored in said audio device is entered manually.

Abstract
An audio device 1 is installed in a motor vehicle with a vehicle security system 2, 3, 4. The radio 1 has circuitry 21 to detect a connection to the vehicle power supply, a microprocessor 11 to inhibit the operation of the radio after an interruption of the connection, an interface 6 and a connection to a bus 9, 10 for communicating data between the radio 1 and the vehicle security system 2, 3, 4, and a data verification unit 15 with a non-volatile memory 13 for verifying data communicated to the radio. Following an interruption of the connection the radio is automatically reset to operational if the data are communicated and verified, and if the data are not communicated or not verified the radio may only be reset manually.
