Application

Your Triad unit was engineered to be installed into the radio's wiring directly behind the radio head. The device was designed to function in any OnStar equipped vehicle to allow a Nokia 2100, 5100, 6100, or 7100 series phone to work hands-free in conjunction with the OnStar system. The Triad, along with the Cellport car kit, will also permit the hands-free phone operation using a Motorola Star-Tac with the OnStar system.

Benefits

Incorporating your cell phone to operate hands-free along with the OnStar system, you will attain the following features:

  • Your hands-free mobile phone installation will allow you to control the volume of the phone with the radio’s volume controls.
  • Your new system will allow you to have a call active on the mobile phone while also allowing you to place an OnStar call (for directions or reservations). Thereby allowing your conversation with OnStar to be heard by the mobile phone caller, thus relieving you of the hassle of repeating the OnStar conversation.
  • If your OnStar system is equipped with "Personal Calling" then you can use your new installation to conduct a 3-way conference call in your car.
  • Most importantly, you will have the safety, convenience, and piece-of-mind of a fully integrated hands-free mobile phone.

Pre-wiring

WARNING! OBSERVE ALL POLARITY CONNECTIONS
Always connect the triad grounds ( black wires ) first
We suggest viewing of the appendix photos on .uhltronics.com
Disconnect the negative terminal cable from the car battery.

TRIAD WIRING COLOR CODE TABLE BY FUNCTION
Black (Blk) = Ground (Gnd)…. -Battery
Red (Red) = +Battery 12V(+30)
Blue (Blu) = Switched +Battery 12V(+15)
Yellow (Yel) = Control Mute (Gnd. Signal)
Violet (Vio) = + Audio
Gray (Gry) = - Audio

Connect the wiring for the Nokia mobile phone car kit to the Triad as follows:

  1. Cut off most of the car kit harness leaving a short (approx. 5" lead)
  2. Crimp or solder and insulate the mobile phone car kit’s red wire to the Triad’s Red 12V (+30) wire in the bundle of wires labeled "PHONE."
  3. Crimp or solder and insulate the mobile phone car kit’s black wire to the Triad’s black (Gnd) wire in the bundle of wires labeled "PHONE."
  4. Crimp or solder and insulate the mobile phone car kit’s blue wire to the Triad’s blue 12V (+15) wire in the bundle of wires labeled "PHONE."
  5. Crimp or solder and insulate the mobile phone car kit’s yellow wire to the Triad’s yellow (Mute) wire in the bundle of wires labeled "PHONE."
  6. Untie the wire harness for the speaker included in the mobile phone car kit if applicable.
  7. Review the illustration, below before proceeding! Using (A) or (B) method, wire the unit accordingly.



  8. Measure six inches from the speaker's phone plug and cut and strip back the wire insulation for both wires, do this for both ends of the cable.
  9. Determine which colored wire is attached to 3.5mm mono phone plug tip. This can be accomplished by using an Ohm meter. Typically the wire color will be red or is the center conductor of a coax cable. The tip connection represents the audio positive signal (+Audio), while the black lead implies the -Audio signal.
  10. Slip the proper length of "shrink tubing" over both sets (+Audio & -Audio) of the cut wires.
  11. Twist the appropriate wires together, such as all the +Audio's signal conductors, described in the above diagram.
  12. Then carefully solder them making a good electrical and strong mechanical joint.
  13. Repeat the steps 11 & 12, but now use the -Audio signal conductors.
  14. Slide the pieces of "shrink tubing" over the solder joints and apply the heat until properly shrunk.
  15. [ Optional Method (B)]. Solder the 3.5mm Mono plug to the Triad PHONE pigtail cable audio input wires, the +Audio should be attached to the phone plug tip at the proper connection location. This audio plug will be inserted into the car kit speaker output jack during the final assembly.
    Note: This configuration will eliminate the car kits' external speaker.

Microphone installation

At this point, you can quickly install the Nokia microphone by following steps 22 & 23 and simply plugging the Nokia microphone into the car kit module. For the OPTIONAL installation (using the internal Saab microphone), perform the following steps.

  1. Route the wires across the top of the windshield under the headliner and down the A-pillar. You can tape the wires to the A-pillar to hold them out of harms way when the A-pillar trim is reinstalled.
  2. Tuck the wire between the dash and the door seal, then between the dash and the A-pillar.

OPTIONAL Microphone wiring ( parts contained in the accessory kit from UHLTronics)

  1. Twist together the two ten foot lengths of wire, brown and white.
  2. Scotch-loc-wiretap the white wire to pin 3 at the microphone - this is your ground wire input for the phone car kit module.
  3. Strip the brown wire and solder it into the electrical pin, Saab Part #40 63 970 and then install it into pin location #2 at the microphone - this is the low level input for the phone car kit module.
  4. Route the wires across the top of the windshield under the headliner and down the A-pillar. You can tape the wires to the A-pillar to hold them out of harms way when the A-pillar trim is reinstalled.
  5. Tuck the wire between the dash and the door seal, then between the dash and the A-pillar.
  6. Route the wires, if possible, away from other wires to reduce the amount of noise pickup, but arriving at the desired location of the car kit module. Cut the wires to the appropriate length.
  7. Solder on the brown wire to the center tip of the 2.5mm Mono phone plug and the white wire to the other conductor on the plug. Then plug it into the car kit module microphone jack.

Making the electrical connections

Important! Locate the electrical pin diagram on the radio housing.
You’re going to be working with the following six wires – Battery power 12V (+30), Battery ground, Switched power 12V (+15), Audio Mute, Tel. In, and Tel. Gnd. Connecting the bundle of Triad wires labeled "RADIO" and "ONSTAR." It may be necessary to remove some of the tape fitted to the factory wiring harness. Take care not to cut the wiring!

  1. Scotch-loc-wiretap the Triad's Gnd. wire in the bundle of wires labeled "RADIO" to the wire at the back of the radio plugged into the Gnd. opening.
  2. Scotch-loc-wiretap the Triad's 12V (+30) power wire in the bundle of wires labeled "RADIO" to the wire at the back of the radio plugged into the 12V(+30) opening.
  3. Scotch-loc-wiretap the Triad's 12V (+15) power wire in the bundle of wires labeled "RADIO" to the wire at the back of the radio plugged into the 12V (+15) opening.

Perform the following steps carefully! In the next few steps we are going to ask you to cut some of the factory wiring to allow the Triad unit to be integrated into the harness. As in the previous step, it may likely be necessary to remove some of the tape fitted to the factory wiring harness. Below is a very basic drawing of the changes you’ll be making in the following steps:

  1. Locate the Tel. Mute wire at the back of the radio.
  2. Cut the Tel. Mute wire about two inches from the radio connector.
  3. Connect the Tel. Mute wire in the radio connector to the Triad mute wire in the bundle of wires labeled "RADIO" using the splice connector.
  4. Connect Tel. Mute wire from the OnStar device in the car's harness to the Triad mute wire in the bundle of wires labeled "ONSTAR" using the splice connector.
  5. Next locate the Tel. In wire at the back of the radio.
  6. Cut the Tel. In wire about two inches from the radio connector.
  7. Connect the Tel. In wire in the radio connector to the Triad +Audio wire in the bundle of wires labeled "RADIO" using the splice connector.
  8. Connect the Tel. In wire from the OnStar device in the car's harness to the Triad +Audio wire in the bundle of wires labeled "ONSTAR" using the splice connector.
  9. Now, locate the Tel. Gnd wire on the back of the radio.
  10. Cut the Tel. Gnd wire about two inches from the radio connector.
  11. Connect the Tel. Gnd wire in the radio connector to the Triad -Audio wire in the bundle of wires labeled "RADIO" using the splice connector.
  12. Connect the Tel. Gnd wire from the OnStar device in the car's harness to the Triad -Audio wire in the bundle of wires labeled "ONSTAR" using the splice connector.

The Triad should be completely connected at this time!

  6. Terminate the onstar call by pressing the white dot button.
  7. Enter a phone number on the cell phone; check that the DTMF tones are passed through the Nokia hands-free speaker.
  8. Place the call by pressing the Send button.
  9. Terminate the call after you have verified that the radio mutes and passes the telephone audio signal on to the car radio speakers.
  10. Turn off the ignition switch, thus initiating the phone function, which shuts down power after a pre-set time interval.

START THE VEHICLES' ENGINE and REPEAT THIS TEST FOR EXCESSIVE NOISE LEVELS as INDICATED BELOW.

FUNCTIONAL TEST OF ONSTAR and CELLPHONE SYSTEM

  • Preset the radio system for a normal listening volume.
  • Functionally test the onstar system by connecting to their personal operator, while the engine is running.
  • Have the operator and yourself confirm the absence of alternator whine noise, by revving the engine.
  • End the onstar call.
  • Place a Cellphone call to another person confirming the proper operation of this "hands-free system".
  • Rev the engine while listening for alternator whine noise.
  • Then terminate the cellphone call.

IF EXCESSIVE ALTERNATOR RELATED NOISE IS PRESENT, THIS WILL REQUIRE THE APPLICATION OF A FILTER.
THIS ALTERNATOR FILTER CAN BE PURCHASED FROM uhltronics

Reinstall all of the removed vehicle components back into their proper positions and secure them. Then reconfirm the operation of this "hands-free" unit, by doing another functional test of the onstar and Cellphone system.

Troubleshooting

Radio will not mute with OnStar or the cell phone. This indicates the radio is not receiving a Tel. mute signal - ground.

  1. Check that power and ground are both present at the Triad.
  2. If okay, check the mute wire from the Triad to the radio.
  3. Ground the mute wire through a 147-ohm series resistor, near the Triad, directly to the chassis. If the radio mutes, replace the Triad.
  4. If the radio does not mute, the problem is in the wire or the radio head.

Radio mutes, but no sound is heard through the Audio system - OnStar AND mobile phone. This indicates the radio is not receiving audio signals.

  1. Conduct resistance checks! Check continuity from OnStar and Cell Phone to the Triad.
  2. Check the wiring between the Triad and the radio.
  3. If okay, replace the Triad.

Radio will mute with OnStar, but not with the phone. The phone is otherwise operating correctly. This indicates the radio is not receiving a mute signal from the phone.

  1. Ground the mute wire directly to the chassis at the phone car kit module.
  2. If the radio mutes, replace the phone car kit module.
  3. If the radio does not mute, ground the mute wire near the Triad with a 147-ohm resistor.
  4. If the radio mutes, check the wiring between the Triad and the phone car kit module.
  5. If the radio does not mute, replace Triad.

Radio will mute with OnStar, but not with the phone and the phone does not charge in the cradle. This indicates that the phone is not receiving 12V (+30).

  1. Check for 12V (+30), 12V (+15), and Gnd. at the Radio bundle at the Triad. If not okay, check the car’s wiring and FUSE.
  2. If okay, check for 12V (+30), 12V (+15), and Gnd. at the PHONE bundle of the Triad. If not okay, replace the Triad.
  3. If okay, check for 12V (+30), 12V (+15), and Gnd. at the car kit module. If not okay, check the wiring between the Triad and the car kit module.
  4. If okay, replace the car kit module.

Radio will mute with the phone, but will not mute for OnStar. This indicates the radio is not receiving a Tel. mute signal from OnStar.

  1. Check that power and ground are both present at the Triad.
  2. If okay, ground the mute wire directly to the chassis at the VIU.
  3. If the radio mutes, replace the VIU.
  4. If the radio does not mute, ground the mute wire near the Triad with a 147-ohm resistor.
  5. If the radio mutes, check the wiring between the Triad and the VIU.
  6. If the radio does not mute, replace Triad.

The phone does not power off when the ignition is switched off. This indicates that the Switched Ignition signal is not present for the car kit module.

  1. Check that 12V (+15) is available at the Radio bundle of the Triad.
  2. If not, repair the problem inside the vehicle’s wiring or FUSE.
  3. If okay, check that 12V (+15) is available at the PHONE bundle of the Triad. If not, replace the Triad.
  4. If okay, check that 12V (+15) is available at the car kit module.
  5. If okay, replace the car kit module. If not, repair the wire between the Triad and the car kit module.

Advanced Troubleshooting

The Triad system does not seem to operate correctly in the way it was designed to function.

Refer to the diagram at the bottom of the page.

  1. Remove the cellphone from the "hands-free" car kit docking station.
  2. Leave the ground (Gnd), black wires attached to their proper location.
  3. Disconnect the wires that are labeled MUTE that go to the OnStar and Cellphone car kit.
  4. Disconnect the wires from the TRIAD that are labeled 12V(+30) and 12V(+15), and are connected to the vehicles car radio wiring harness. These wires are part of the cable marked RADIO, coming from the TRIAD device.
  5. Connect the 12V(+30) and 12V(+15) together and attach them to the negative (common) black lead of your current meter.
  6. Connect the positive red lead of your current meter to the 12V(+30) located in the vehicle car radio wiring harness.
  7. Place the current range of your meter to the 200mA scale, or a alternate current range around this suggested value.
  8. With both, OnStar and the Cellphone MUTE control wires open, the measured current value should be less than 5mA.
  9. When the MUTE control wire from the Cellphone is connected to ground, through a 147W resistor. The measured current value should be less than 100mA.
  10. With the Cellphone control MUTE wire still connected as stated above, connect the OnStar MUTE control wire through a147W resistor to ground. The measured current value should be less than 30mA.

If these typical current values are not in this stated range, the TRIAD is probably damaged. Please call or e-mail UHLTronics.
