If your KENWOOD unit is experiencing audio problems (NO Audio), but do have audio when TUNER is selected as the source, you may have problems with your installation.

NOTE: If using an external amplifier or the unit was installed using a separately purchased wiring harness for your specific vehicle, please check the following

If Using an External Amplifier

The P.CONT or REMOTE terminal on the external amplifier requires a “turn on” signal from the stereo. This terminal should be connected to the BLUE/WHITE P.CONT wire on the Kenwood harness and not the solid BLUE ANT.CONT wire.

If Using a Vehicle Specific Harness
The vehicle has a factory installed amplifier and requires a “turn on” signal from the stereo. Make sure that the BLUE/WHITE P.CONT wire is connected to the vehicle specific harness and NOT the sold BLUE ANT.CONT wire.

The solid BLUE ANT. CONT wire is used to trigger a power antenna ONLY when the tuner is selected as the source. Using this wire to “turn on” an external amplifier or factory installed amplifier will only allow it to work when TUNER is selected. Please refer to your instruction manual for proper installation. If you are not completely comfortable with installing the unit yourself, we recommend that you seek assistance from a professional installer.

Will the Kenwood KDC 1032 RCA outputs work with an ipod adapter similar to an aux output? If so, how?

Hi, if you are trying to get your I-pod to play through your car stereo, then you would need to have the RCA inputs, not outputs. If you connect your i-pod to the stereo outputs it won't work because both things are trying to push sound out of their outputs. If you connect the adapter to the stereo's inputs then it would work.

I believe You have to have the right auxillary connection to plug it in -- looks like in the lower right hand corner if you are looking directly at the unit.

Linking an i pod to a Sony CDX-MP40 using the bus input terminal

Some Sony head units let you use the Bus audio inputs as an auxiliary source input, but yours is not among them. To play your iPod through the head unit, you'll either need an iPod interface module: or an auxiliary input module: The iPod interface will allow you to control and display the iPod directly through the head unit, while an auxiliary input adapter will allow the iPod to play through the head unit using the iPod's controls and display.
