Installation
Remove the factory radio.
The MBZNAUX1 will connect directly to the
rear panel of the factory radio. Referencing the factory service manual
instructions, remove the factory radio. If you feel this process is beyond your abilities, we
strongly recommend having the work done by a mobile electronics specialist.

Assemble the components shown on page 3 and connect them to
the MBZNAUX1 module.
Use the diagrams on page 3 and 4 to assemble
the components that will connect to and control your Zune device.
Power connector wiring.
Connect the black wire of the power connector shown on page 3
to a clean, bare-metal chassis ground. When in doubt, measure the resistance between
potential grounding points and the vehicle battery using a multimeter. Choose a grounding
point with equivalent resistance as other grounded components in the audio system. Connect
the red wire to a +12V switched (ignition) power source. This wire requires a 12V, 1500mA
inline fuse. MAKE CERTAIN THAT REPLACEMENT FUSES MATCH THESE SPECIFICATIONS.
RCA connections.
The MBZNAUX1 module has two pairs of female RCA connectors labelled
“INPUT A” and “INPUT B”. For simplicity, connect the male RCA audio cables (from the RCA
component A/V output breakout shown on page 3) to the female RCA connectors labelled
“INPUT A”; this connects your Zune device to “INPUT A”. You may optionally connect an
additional low-level audio input source to “INPUT B”.
