Electrical Connections
To avoid the aggravation of costly mistakes and serious damage, please carefully read all of the
instructions before you begin. Carefully follow all instructions.
General Recommendations
• If you’re not confident that you can install the unit correctly, have it installed by a qualified
Blaupunkt installation technician.
• Use this unit only with negative ground 12 Volt (11-16 Volt) direct current (DC).
• Be sure to detach the faceplate before you start to connect or install the unit.
• We recommend making and testing all electrical connections before installing the unit.
Connect the leads (wires) according to instructions and diagram below.
Electrical Connection Instructions
1. Disconnect the vehicle battery’s negative terminal before making connections.
2. Connect the speakers and/or external amplifiers (if you have any) following the guidelines in
the “Speaker Connection” section below.
3. Connect the antenna output lead to the antenna motor trigger input terminal (if you have
one). The total amperage required of the antenna lead must not exceed 100 mA. Do not
connect the antenna lead to the antenna’s power supply input.
4. Connect the ground lead to a grounded metal part on the vehicle. We recommend
grounding all audio system ground leads (head unit, external amplifier, etc.) to a common
grounding point, preferably a non-painted surface under the instrument panel.
5. Connect the battery input lead to a source of constant battery power, preferably a terminal
to an appropriate slot in the fuse box.
6. Connect the ignition input lead only after the other leads are connected. Be sure to connect
the ignition lead to a positive (+) 12 Volt power terminal that is energized only when the
ignition key is set to the on position or accessory position.
7. Cover the ends of any unused leads with electrical tape. This will prevent them from
touching the vehicle or each other and causing a short-circuit and damage to the radio or
vehicle.
8. Reconnect the vehicle’s battery.
9. Verify that no fuses have blown.
10. Plug the harness into the unit.
