i cannot for the life of me change my presets or set them or atleast change my selector to manual. even on auto it does not scan and pick up the correct stations that come in. the owners manual is the hardest thing to read and understand which anyone with this model shall know. it also has the same instructions manual as a kdc-bt742u. and kdc-x493
any help would be great.
also here is a link to the head unit if that helps.
