2: Argos installation procedure
Gaining access to the location
1. You will need to remove the right side trunk liner to
install Argos™. The first step is to remove the
door/flap. Then, taking up the trunk carpet will make
the next steps easier.
2. The trunk side liner is held in place by a black plastic
pin and a black plastic hook all the way forward. The
pin can be pried out with a small flat head screw driver. The trunk liner can then be
pulled away from the inside of the trunk. It is OK to bend the liner a little - it is quite
Connecting Argos™ to your vehicle requires using two connectors. One is a 25pin con-
nector that sometimes has a grey colored clip on it and a black colored Fiber Optic con-
nector that has orange fiber cables coming from it. This connector may be straight or
have a 90° angle. CAUTION - take care handling the Fiber Optic cable so as not to
damage it by bending to tightly or crimping it.
You will use these connectors directly with Argos™. (Note-skip the following if you are
replacing an old MB phone system): The next step you will need to perform will be to in-
corporate the Fiber Optic cable that you found into the Fiber Optic communication loop.
There will be the other end of this phone cable a little further up in the trunk forward of
the spare tire and under the plastic “floor.”
In this picture you see that the fibers are looped and connected together (to themselves
at this point) by a small black connector. You will need to open up this connector (the
label will say TEL) and you will see that there is a red and clear end. You will want to
connect one end to the connector on the car that is already in the loop. This is the back
connector that doesn’t loop around itself. And then connect the other end to the remain-
ing end with the remaining connector. You are “daisy chaining the connectors.” Note
that the red and clear ends are different and they will only go in one way so that you

won’t get the ends mixed up. The “chain” will go from clear to red to clear to red, etc.
Here is an Exploded picture of the daisy chain.
Attaching and Mounting Argos™
Note that your vehicle may be different than depicted.
If your vehicle doesn’t have an old MB phone module, your options for mounting are
simple as shown below. If your car was previously equipped with a telephone module
(TCU) simply unplug that module and plug Argos™ in taking care to use the pictured 25
pin connector with the gray flaps and not the one directly connected to the TCU. First,
perform a “dry run” by finding the cables you need, hooking them up to Argos and verify-
ing they will reach and fit without crimping in the location of your choice.
Remember, NEVER crimp or fold the Fiber Optic cables. Argos™ can simply be
mounted with tie wraps to the trunk support arm and this is a good choice in this vehicle.
These are merely mounting suggestions, you may mount your unit wherever is conven-
ient in your application. We do recommend mounting with the connectors facing up.
This will help place the internal Bluetooth® antenna in a more optimal orientation. An-
other way to think of this is to try to have the Argos™ arrow pointing to the passenger
compartment if possible.
3: Display and head unit Operation
Note: For pairing procedure see step 13
1. To the right is the standard radio display with Argos™ installed (note the TEL signal
strength indicator now in the upper right hand corner).
2. Upon pressing the TEL button on the radio, you will enter the standard telephone
display mode (READY is displayed).
3. The signal strength meter is used to indicate two things.
The meter will show either 5 bars or 0 bars. 5 bars indi-
cates a connection to the Bluetooth phone. 0 bars indi-
cates that your vehicle and phone are not connected. Ba-
sically if you have 5 bars you can place a call from the ra-
dio; if there are 0 bars then you cannot.

4. From the READY mode, you can:
Activate pairing or connect to a previously paired phone.
Dial a number from the key pad to place a call.
Scroll through your main phonebook and recently placed call list.
Activate voic e dial on y our telephone.
Disconnect the car from the phone.
5. Access phonebook entries (if applicable) is done from the READY mode by using the
four arrow keys. The up and down arrow move forward and backward one entry at a
time in your list whilst the left and right arrows skip to the next letter in the alphabet.
L1 will be indicated in the upper right hand corner.
6. To scroll through your recent call list from the READY mode, press the SND button.
You will see the most recent call made, you can now scroll recent calls with the up
and down arrow keys (note the L2 in the upper right hand corner indicating the “lo-
cal” recent call list). Pressing SND again will (on some headunits) will bring you to
missed calls and received calls lists.
7. From the telephone display READY mode you may place an outgoing call. Use the
dial pad keys to enter the phone number or select an entry from your phonebook and
press the SND button. If you see NO SERVICE displayed when you try to place a
call, this indicates that you are in an area with no cell phone coverage.
8. When an incoming call is received, the display will switch from whatever mode it is in
to the telephone mode. The display will indicate CALL or will show the incoming
Caller-ID if available. Any audio programming will mute and a ring tone will be
heard. Press SND or the off-hook steering wheel button to accept the call.
9. From the READY state you can also activate Voice Recognition if your phone is so
equipped. There is a permanent entry in your phonebook that will command the
phone to accept your voice command. Once you select that entry and press SND,
wait a moment (some phones will produce a confirmation beep) and say the voice
tag that you have recorded in your phone.
10. During a call the indicator will display CALL. Phone mode volume can be adjusted
via the radio volume knob or the steering wheel volume control. During a call a but-
ton labeled MUT is also available. Pressing this will mute and un-mute your micro-
phone (you will hear a light confirmation tone every few seconds indicating your mic
is muted). Another feature that is active during a call is full DTMF tone generation so
that you can used the keypad to enter numbers during a call - helpful if you need to

enter voicemail passcodes, etc. Press END or the on-hook steering wheel button to
end the call. Normal audio programming will resume.
11. You may see the message “PROCESSING” if you try to access your phonebook
immediately after starting the car. This message indicates that the phonebooks are
being uploaded to the car. This can take up to two minutes. If you try to place a call
from the radio during this process, you will receive the message “NO SERVICE” -
simply wait a minute and try again.
12. During a call, your in-car electronics will stay active even after you shut the car off
and remove the key. Once your call has ended, the electronics will turn off automati-
13. To initially configure you phone and car to work together: from the READY screen
(with 0 bars), using the arrow keys on the head unit you will see only two choices,
one for “CONNECT” and one for “PAIR PHONE.” Press the SND key when you are
on the “PAIR PHONE” choice. Then go to your cell phone and have it search for
Bluetooth® devices. It should find ARGOS. Then select ARGOS on your phone and
enter the pass key. Your passkey will be 1234. Once the pass key is accepted, turn
off the ignition and wait 30 seconds. Turn your ignition back on and monitor your ra-
dio display and telephone. If your phone and car immediately connect then your
pairing process is complete. If, however, they do not automatically connect simply
select ARGOS on your mobile phone and manually connect to ARGOS (some
phones require you to initiate the connection from the phone before allowing auto-
matic connections). Once you have done this ONCE and get the 5 bars, from then
on your phone and car should automatically connect every time you start your car.
Note that you can also use the “CONNECT” option to manually connect and discon-
nect the phone and the car. You may need to configure your phone to make the
connection to ARGOS automatic or to make ARGOS “trusted” by your phone.
14. You may pair up to 5 phones with the Argos unit. Simply repeat the process for each
phone you would like to add. Note that only one phone can be used at a time.
15. Argos Reset: Should it be necessary, you can reset your Argos™unit to factory de-
faults by dialing the following command and pressing SND. Note that all previous
pairing information will be lost. From the READY state, dial *301#2002# and press

Your Argos™ unit was designed and programmed to support as many Bluetooth® wire-
less technology equipped phones as possible. There are a number of factors that con-
tribute to Argos™ and phone compatibility including the software version in your phone.
Some phones do not support the functionality required for download of your phonebook.
Those phones that do support phonebook download may download the entries you have
stored in the phone or on the SIM card or in some cases both. If you have only some
entries or no entries you may wish to check where your phonebook is stored in your
phone. You may also find it convenient to utilize your phone’s keypad while in your car.
For example, you may dial a number from your phone and press send on your phone
and still talk handsfree through the car’s system and then press the hang up button on
your steering wheel to end the call.
C CLASS special note: On some later vehicles, MB did not Pre-Install the fuses necessary to utilize a
phone. If you have attached everything but you get no functionality, the first step will be to check your fuse
panel and verify that fuses are installed in all applicable locations (in some cases there are up to 4 fuses that
are needed for the telephone to operate. Please consult your owners manual for fuse locations.
