ABSTRACT:
A theft-resistant audio system for a vehicle including a housing or chassis enclosing a digitally-controlled audio signal source and microprocessor-based controller therefor which is securely and permanently mounted to the vehicle behind the dashboard, and a user interface unit containing manual input controls and an audio system status display which is pluggable into the front of the permanently secured housing through an opening in the dashboard to facilitate removal thereof when the vehicle is unattended to thereby render the audio system unusable and hence of little value to a potential thief.
