A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact.

Method and apparatus for sensing inter-modulation to improve radio performance in single and dual tuner

A method of operating a vehicle includes receiving a radio frequency signal and determining that the radio frequency signal has at least one characteristic indicative of the vehicle entering a tunnel. A setting of a vehicle system is automatically modified in response to the determining step.

Method for drive personalization based on tunnel detection for a single-tuner system

A method of operating a single-tuner radio includes tuning into a first frequency. A pause in a first signal associated with the first frequency is detected. Tuning is switched from the first frequency to a second frequency during the pause. Fieldstrength, multipath, adjacent channel energy, frequency offset and FM modulation for the second frequency are measured. Tuning is switched from the second frequency to the first frequency. Tuning is switched from the first frequency to the second frequency dependent upon the measuring step.

Method and apparatus for utilizing modulation based audio correlation technique for maintaining dynamic FM station list in single tuner variant and assisting alternate frequency switching methodology in single tuner and dual tuner variants

A method of operating an audio system in an automobile includes identifying a user of the audio system. An audio recording playing on the audio system is identified. An audio setting entered into the audio system by the identified user while the audio recording is being played by the audio system is sensed. The sensed audio setting is stored in memory in association with the identified user and the identified audio recording. The audio recording is retrieved from memory with the sensed audio setting being embedded in the retrieved audio recording as a watermark signal. The retrieved audio recording is played on the audio system with the embedded sensed audio setting being automatically implemented by the audio system during the playing.

Method for driver personalization based on tunnel detection for a single-tuner system

A method of configuring a tuner includes scanning at least one range of radio frequencies, measuring a signal quality metric for each of a plurality of the frequencies, and selecting a set of operational frequencies for the tuner. The selecting step is dependent upon the measuring step.

Method for automatic frequency range and step selection using region signature for a digital AM/FM tuner

A method of configuring a tuner includes sampling a radio frequency and measuring at least one signal quality metric for the sampled frequency. It is determined whether there is co-channel interference on the sampled frequency based on the measurement of the at least one signal quality metric. The sampled frequency is selected as an operational frequency for the tuner if it was determined in the determining step that there is an absence of co-channel interference on the sampled frequency.
