My sony //cd amfm with detachable face keeps losing the memory
whenever I remove the detachable faceplate. I follow the instructions to store stations and they hold until I shut the car off
or remove the faceplate. Any suggestions

Hi,
Sounds like you have the Yellow constant wire of the radio on a keyed line instead of the battery hot all the time. Check it out with a test light and see if the Yellow wire goes off with the key. If it does just move the Yellow wire to a hot always line.

Thanks for your advice I removed the yellow wire and connected to a hot always wire. I am listening to the music stored as I attach my detachable face to the radio. Your advice saved me and the radio. Thanks again
