InCarTec 29-UC-050-SAAB Steering Wheel Control Interface
Product Information
The SAAB Steering Wheel Control Interface (Model No. 29-UC-050-SAAB) is a device that allows for the retention of steering wheel controls when replacing the original head unit in SAAB cars manufactured from 2006 onwards, except for SAAB 9-3 (06-13) and SAAB 9-5 (06-10) without OEM navigation. The interface has input and output connections for GM LAN BUS, Illumination, SWC Data, 12V Ignition, 12V Permanent, SWC Ground, Reverse 12V Output, Speed Pulse Output, and SWC RES Output. The interface comes with a patch lead and two 8 pin ISO connectors for connecting to the aftermarket head-unit.
Product Usage Instructions
- Connect the cables to the interface box and to the car, and the patch lead to the 4 pole black connector (this is attached to pins 4, 8 and 12 of the control box). Connect the two 8 pin ISO connectors and the patch lead to the aftermarket head-unit. When connected to the car the interface will automatically recognise the vehicle. The green LED on the interface will repeatedly flash once followed by a pause.
- You need to set the interface to the brand of head unit you are fitting. The number of flashes between pauses corresponds to the make of head unit, see the table below for the number of flashes needed for each one. Press the VOL + and VOL – buttons on the car’s steering wheel to increase or decrease the number of flashes. When you have the correct number of flashes, press SEEK+ to confirm and the LED will go to a solid green.
- If fitting a Chinese or resistive programming head-unit, set the number of flashes to 6. Confirm the setting by pressing SEEK+. Now press the reset button 5 times, the interface will start to flash yellow (this allows prolonged pressure on the steering controls). Using the radio’s resistive learning menu, you can now learn and memorize the buttons. Wait at least 5 seconds between each button press. When finished, turn the ignition off and on, and the LED will go back to solid green.
- To reprogram the interface for another head unit brand or if the light is solid green before you have had the chance to set the head-unit brand, push the reset button in and keep it pushed in for 10 seconds and then release the button. At this point, the LED should start to flash green.
- If fitting an Alpine head unit, set jumper J1 (see overleaf for details).
- To set the jumpers, locate them on the PCB inside the interface box. By default, they are set up to suit most vehicles and should usually only need to be changed if fitting an Alpine head unit. The jumpers are set by moving them between positions 1 and 2 or positions 2 and 3.
- The reverse output (blue wire) is only needed when fitting a reverse camera to the new head unit. The grey speed pulse wire is needed when fitting head units with built-in satellite navigation and some Kenwoods. If not required, these can be insulated and ignored.

CONNECTION
Connect the cables to the interface box and to the car, and the patch lead to the 4 pole black connector (this is attached to pins 4, 8 and 12 of the control box). Connect the two 8 pin ISO connectors and the patch lead to the aftermarket head-unit. When connected to the car the interface will automatically recognise the vehicle. The green LED on the interface will repeatedly flash once followed by a pause.
You need to set the interface to the brand of head unit you are fitting.
The number of flashes between pauses corresponds to the make of head unit, see
the table below for the number of flashes needed for each one. Press the VOL +
and VOL – buttons on the cars steering wheel to increase or decrease the
number of flashes. When you have the correct number of flashes, press SEEK+ to
confirm and the LED will go to a solid green.
For Chinese and resistive programming head-units.
Set the number of flashes to 6. Confirm the setting by pressing SEEK+. Now
press the reset button 5 times, the interface will start to flash yellow (
this allows prolonged pressure on the steering controls ). Using the radios
resistive learning menu you can now learn and memorize the buttons. Wait at
least 5 seconds between each button press. When finished turn the ignition off
and on and the LED will go back to solid green. To reprogram the interface for
another head unit brand or if the light is solid green before you have had the
chance to set the head -unit brand. Push the reset button in and keep it
pushed in for 10 seconds and then release the button. At this point the LED
should start to flash green.
| Number of flashes | Make of head unit |

| 2 | Kenwood 1 wire |
| 3 | JVC 1 wire |
| 4 | Alpine 3.5mm |
| 6 | Pioneer 3.5mm jack Resistive 2 wire Resistive 3.5mm jack |
| 7 | Sony 3.5mm jack |
Setting the Jumpers
The Jumpers are on the PCB inside the interface box. By default they are set up to suit most vehicles and should usually only need to be changed if fitting an Alpine head unit. The jumpers are set by moving them between positions 1 and 2 or positions 2 and 3.
| Position 1-2 | Position 2-3 | |
|---|---|---|
| J1 | Alpine | All other Radio Manufacturers |
| J2 | Negative Handbrake (not all vehicles) | |
| J3 | Positive Reverse Output | |
| J4 | ||
| J5 | CANbus Handling |
The Reverse and Speed Pulse cables.
The reverse output (blue wire) is only needed when fitting a reverse camera to
the new head unit. The grey speed pulse wire is needed when fitting head units
with built in satellite navigation and some Kenwoods. If not required these
can be insulated and ignored. Make sure the patch lead is connected to the 4
pin plug on the interface and the input on the new head unit. 29-UCCAB patch
