Question about JVC KD-PDR30 CD Player
Check to make sure you don't have the batt+ wire and switched 12v wire mixed up. batt+ is usually yellow or orange while the switched 12v wire is usually red, consult the manual or look on the unit itself. there should be a wire color description there. batt+ is what you want 12v running to all the time to keep the settings. switched 12v is the one that turns the unit on when the key is turned on. the unit will still operate if the 2 are backwards but like you said it will clear the memory every time you shut it off because your cutting power to the batt+ wire thus resetting the unit.
