AIWA CD changers are remarkably compact, providing convenient multi-disc playback capability in a minimum of space. You can choose the ultra-compact 10-disc changer for maximum continuous playback time. Or, if space is at an absolute premium, choose the ultra-compact 6-disc model. The 6-disc unit is small enough to be installed in the passenger compartment, so you dont have to go back to the trunk to load or change discs. AIWA CD receivers with CD Changer Control Capability enable you to control all of the playback functions of the (6-disc or 10-disc) 10-disc AIWA changer from your in-dash unit. This makes it unnecessary for you to use a separate control panel or remote control to operate the changer. Only can be used with another Aiwa CD player from the "M" series.
