Traffic Safety and Precautions
• Do not adjust your unit in difficult driving conditions that demand your full attention.
• As the driver of a motor vehicle, it is your responsibility to pay attention to the traffic situation
at all times. Never use your unit in a way that could distract you.
• Always make sure that you are still able to hear any warning signals coming from outside of
the vehicle, such as police or fire engine sirens, so that you can react accordingly.
• If your vehicle was parked in direct sunlight resulting in a considerable rise in temperature
inside the vehicle, allow the unit to cool off before operating your unit.
• You are cautioned that any changes or modifications not expressly approved in this manual
could void your warranty.

Detachable Face
Detaching & Attaching the Face:
The face of this unit can be detached and taken with you to prevent it from being stolen.
Detaching the Face:
Press the REL (Release) Button and detach the face by gently pulling it off as illustrated.
Note: Do not pull it straight out from the chassis. Be sure not to drop the face when detaching it
from the chassis.
Attaching the Face:
Apply the right hand side of the face to the chassis by sliding (part B) of the face to (part A) at
the front of the chassis. Gently push the left side of the face against the front of the chassis until
it snaps into place.
Note: Make sure that the face is inserted right side up. Do not press against the display window.
Do not press hard against the face when attaching it to the chassis, it may be easily attached
with gentle pressure. Do not expose the face to direct sunlight, heat sources such as hot air
ducts or leave it in a humid place. Never leave it on the dash board of a vehicle parked in direct
sunlight, where there may be a considerable rise in temperature inside the vehicle.
Affixing Faceplate For Retail Display:
The faceplate can be affixed to the unit’s chassis, which is desirable for a retail display, for
example. This should only be done in situations where the unit can be accessed from
behind the mounting surface. Once the faceplate is affixed, the release keys cannot be
used to remove the chassis.
To affix the faceplate:
Insert the black bolt into the hole at the left front of the top of the radio. See* below.

Electrical Connections and Installation
Please carefully read all of the instructions before you begin. Carefully follow all instructions.
You’ll be glad you did!
• 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.
Disconnect the vehicle battery’s negative terminal before making connections.
Connect the speakers and/or external amplifiers (if you have any) following the guidelines in
the SPEAKER CONNECTION section below.
3. Connect the blue (trigger output) lead to the antenna motor trigger input terminal (if you
have one). The total amperage required of the blue lead must not exceed 300 mA. DO NOT
connect the blue lead to the antenna’s power supply input.
4. Connect the black (power ground) lead to a grounded metal part on the vehicle. We
recommend grounding all audio system black ground leads (head unit, external amplifier,
etc.) to a common grounding point, preferably a non-painted surface under the instrument
5. Connect the yellow (constant power) input lead to a source of constant battery power,
preferably a terminal to an appropriate slot in the fuse box.
6. Connect the red (turn-on power) input lead only after the other leads are connected. Be sure
to connect the red 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
8. Reconnect the vehicle’s battery.
9. Verify that no fuses have blown.
10. Plug the harness into the unit.
11. Attach the faceplate and test the unit.
Once the connections have been successfully made, you can begin to mount the unit.

system, all hereafter referred to simply as “speaker”) to each of the units’ four pairs of
speaker leads.

• Carefully choose the mounting location so that the unit won’t interfere with normal driving.
• Avoid mounting locations where the unit would be subject to high temperatures, such as from direct
sunlight or hot air from the heater, or where it would subject to dust, dirt or excessive vibration.
• The illustration below shows a typical installation, however, you may need to adjust the
installation, depending on the unit. If you have questions or need additional installation
hardware, consult your Blaupunkt dealer.
• Make sure the unit is firmly anchored (preferably at both front and back) and does not vibrate.

Mounting the Unit in a Japanese Car
You may have difficulty mounting this unit in some Japanese cars that have ISO mounting
In this case, consult your Blaupunkt dealer.
1 Run a blade along the slits on the back of the front trim ring, unscrew the two side screws,
and separate it from the unit. Save the trim ring and related hardware in case you ever want
to install the unit in another vehicle.
2 Use the vehicle’s own mounting hardware to attach the unit.

Radio Operation
Last Station Memory
Each FM bank and AM band has its own last station memory which holds last-tuned frequency
for that band or bank irrespective of whether that frequency is stored into a preset.
Selecting Bands
Press SRC as needed to access FM1, FM2, FM3/FMT, AM/AMT banks.
Seek Tuning
Press /\ or V to seek next receivable frequency. Tuning stops at frequency that fulfills sensitivity
requirements predetermined by sensitivity set through SENS/LD button.
Tuning Sensitivity (SENS)
Press SENS/LD for more that 2 seconds to switch between local (lo) and distant search
Radio Reception Hints
• When listening to weak or distant AM stations, adjusting the Treble to minimum (-7) will
reduce noise and improve sound.
In general, set SENS to DX if in rural areas or where stations tend to be weak and distant,
and to LO when in metropolitan areas or where stations tend to be strong and local.
Stereo Symbol
Stereo symbol turns on if a stereo station with an incoming signal of at least 20 dBµV is
received. The unit gradually switches between mono to stereo automatically.
Manual Tuning
Press /\ or V for more than 1/2 second and frequency will go one channel/step in direction
pressed. Press and hold causes continuous manual tuning. Unit returns to seek tuning mode
after 4 seconds or after storing a station on a preset.
Preset Station Storage
After tuning desired frequency on desired band, press and hold a Preset Button for more than 2
seconds to store current frequency. Audio is muted during storage, preset number appears, and
beep acknowledges storage.
Preset Station Selection
Press desired Preset Button.
Travel Store
In any FM Bank, press SCA/TS for 2 seconds to activate FM Travel Store. (In AM Bank, press it
for 2 seconds to activate AM Travel Store.) TS appears. Beginning at the bottom of the band, TS
stores five relatively strong stations and returns to preset 1. Pressing any tuning-related button
cancels search operation.
