Radio problem
I have searched this forum for info on a problem with my C6 coupe with XM radio--no nav.
The radio has already been replaced once and still the same problem.A preset will at times ,play audio for about 2seconds .Then the audio stops and the only way to correct the problem is to reset the preset again.The happens on the FM band.
Any ideas?
Thanks

Radio Presets Change and Audio is Lost (Set Radio Alternate Frequency (AF) to OFF)
2005 Chevrolet Corvette,
with CD Player MP3 Radio (RPO US8) or CD Changer MP3 Radio (RPO US9)
Condition
Some customers may comment that when they recall a preset FM Radio Data System (RDS) station, the audio is lost and the station fades out for approximately 45 to 60 seconds and then returns.
Cause
Radios are manufactured with the Alternate Frequency (AF) default setting to "AF ON". When the AF function is on, and the radio station becomes weak, it will attempt to seek to another stronger station that carries the same program. This functionality has limited use in the domestic market, where individual competing radio stations do not carry the same program - unlike in export markets, where there are chains of stations all carrying the same program.
Correction
Change the radio alternate frequency to off. Review the vehicle's Owner's Manual with the customer, especially how to turn on and off the AF function. Press and hold the BAND button for two seconds. After two seconds, a beep will be heard and the radio screen will display the current AF setting (AF ON or AF OFF). If the AF setting is on, press and hold the BAND button again for two seconds. AF OFF will appear on the display.
