Product fits as advertised, connectors are the same. Radio & CD player work fine, except the CD player makes a repetitive sound that is consistent with something rubbing on a moving part- it is not through the speakers as I can hear it whether the volume is turned all the way down or is playing music. The outer metal box frame was rusted in spots- obviously this unit came from another vehicle. The face plate was in very good condition. The "Aux." jack that was added works perfectly so far with my MP3 player. The On/Off function does not work! The volume knob can be pushed in (normally Off), or protruding (normally On). The unit does turn off with the ignition key, so I don't have to worry about battery drain, but it is a flaw.
