Connecting the cables
1. Plug the black ISO connector into the cars original radio connector.
2. Connect the brown and black ISO connectors to the new radio.
3. Connect Handbrake, Reverse and Speed Pulse outputs to the aftermarket head unit (if required)
4. Connect the correct patch lead (29-UCCAB-***) to the aftermarket unit.
Additional tap off loom
On some vehicles the 29-uc050-Ren1 cannot decode the ACC on signal from the CAN bus and the vehicle may not
have the wire in the vehicle’s connecter.
In these circumstances it is necessary to use the additional Tap off fuse supplied to provide an ACC signal for the
radio to sense the ignition key on signal.
This is designed to connect to a switched supply in the fuse box that shuts off when the ignition key is off.
Find a fuse that switches with
the key. Remove the fuse from
the fuse box and insert this in
the tap off fuse holder and
push the new fuse holder in
empty space that the original
fuse was removed from.
On the fuse box below (Renault
Traffic 2011 we used the radio
10-amp location)
Your vehicles fuse box maybe
different.

Setting the interface correctly
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.
How the flashes work Number of
Make of head unit Colour and Frequency
flashes
The flashes of the LED follows this behaviour:
1 Clarion 3.5mm jack 1 Green Flash
LED GREEN flash means = units
2 Kenwood 1 wire 2 Green Flashes
LED RED flash means = tens
3 JVC 1 wire 3 Green Flashes
LED YELLOW flash means = hundreds 4 Alpine 3.5mm 4 Green Flashes
5GREEN flashes indicate the radio in position 5 Pioneer 3.5mm jack
2 RED flashes indicate the radio in position 20 6 Resistive 2 wire 6 Green Flashes
Resistive 3.5mm jack
1 RED flash followed by 2 GREEN flashes indicate
7 Sony 3.5mm jack 7 Green Flashes
the radio in position 12.
90 Alternative Resistive 9 Red Flashes
1 YELLOW flash indicates the radio in position 100
If fitting an Alpine set jumper J1, see bottom of sheet
Please Note
Alternative resistance setting is 90 flashes. This often works if the standard Chinese and resistive setting fails to work.
For Chinese/ 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 in-
terface 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.
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 posi-
tions 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

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 Kenwood’s.
If not required these can be insulated and ignored.
Connecting the patch lead
Make sure the patch lead is connected to the 4 pin plug on the interface and the input on the new head unit.
