the dealer-fitted Grundig radio-cassette unit died a death. Have replaced it with a Panasonic CD-radio. Trouble is, every time you turn it off it loses all the stored radio stations. According to tthe Panasonic 'troubleshooting' guide this could mean that the battery is disconnected or power cord removed - which it isn't, obviously. Puzzled.... Any thoughts would be appreciated. The replacement fitted without a problem - the black block things just fitted straight in, although the third one (for separate dashboard display, is redundant now. Thanks for any suggestions..............
