The cassette player on my '79 300D will not accept the tape. It simply does not allow the tape to "click" into position.It just pops back out without locking. The eject button is in it's proper place. The radio works fine, with the exception of the antenna only extending about 1/4 of the way.
FYI It is the Blauplunk Mexico, AM/FM Cassette with auto change bar. (No buttons).

Thank you,

Joe
