[Solved] Activating AUX on Laguna III 2008 Cabasse Tronic Navi with Alpine Changer: How-To

Best answers

How can I activate the AUX input or CD changer on a 2008 Renault Laguna III Cabasse Tronic Navi radio so I can connect an iPhone or Bluetooth module?

You usually have to enable AUX/changer in the radio configuration first, either in the Expert Menu or at a Renault dealership with CLIP; on some Cabasse Tronic/Carminat units the Expert Menu is not available, so dealer activation is the working method [#10356779] [#11875652] [#19754842] If you want to use a Bluetooth/AUX module, connect it directly to the radio’s yellow mini-ISO C1 socket, not through the intermediate harness, and if the plug does not fit, cut the two guide rails/protrusions so it seats correctly [#19754842] [#21370123] [#21370154] One reported working setup is to shift the pins in the module’s green plug to match the Cabasse pinout, where the audio lines are wired on the appropriate C1 positions and pins 2 and 5 are bridged [#19754842] [#19921689] [#20279336] In that configuration, users reported that the AUX menu appears and music playback works after activation [#20279336] [#21370174]

    Hi, I have a Laguna with Cabasse Tronic radio and company navigation. I wanted to hook up the changer to the mini ISO blue connector and possibly connect to the cable with the audio from the iPhone, but when I activate the changer (Alpine from Renault Espace) nothing happens, i.e. the radio does not see the changer. Please let me know if there is any way to activate the input, is the changer incompatible or something else? I should add that the changer is original Renault, the cable included fits into the socket on the radio (mini ISO blue).
    Maybe someone has another idea for connecting an MP3 to this radio (the radio has an inactive AUX). I'm not interested in a transmitter connection, the radio has Bluetooth but I think it's only for the phone, I've not been able to use it to listen to music.

    I do not know if my friend has already solved the problem, but I know for sure that activate the aux input and the ability to connect the changer, you have to go to the Renault Dealership there, podepną under Clipa and activates these options. I have the same radio and I did it.

    tomato999 - a long time has passed, but you may know or remember. Mam Carminata - http://nawigacjefabryczne.pl/pliki_do_pobrania/carminatinformee2bt.pdf - it looks like you have / had one.
    Do you know where the microphone for the hands-free kit comes in from behind? I have a problem, that I can not hear me when I phone my phone through Blue. I hear the interlocutor, the voice goes to the speakers, but the interlocutor does not hear me. I see this feler in the defect of the microphone. Do you know anything maybe?

    the microphone is probably near the lamp (above the mirror) there are holes you need to get there and replace it because the loud-speaker set is not on the radio only rather under the board.

    It's time to dig up the topic, Lord tomato999

    So far I am a happy owner of Laguna III, BT0H, 2.0 T 170KM, Radio TYPE: RAD02 , Navigation system level: NINAV6 , Vintage car 03.2008

    The main guest, that is: Radio Carminat Cabasse Tronic
    1: https://obrazki.elektroda.pl/5768834200_1639104842.jpg
    2: https://obrazki.elektroda.pl/6311704500_1639102129.jpg

    First of all, like the above-mentioned colleague, I have a radio in which there was no aux, and the aux mode could not be turned on from the EXPERT Menu (because it is not there), and you could only turn on the CLIP.
    Secondly, the subject of the yellow mini ISO cube [C1] was on the agenda. Well, a friend's plug on the radio, as in mine, is not plugged directly into the radio, but through ... I don't know what to call it - distance? In any case, the yellow bone has no electrical connection to the radio.
    3: https://obrazki.elektroda.pl/1558393700_1639105014.jpg

    I was tempted to see what would happen if I stepped on her directly. I did it and the AUX mode appeared on the display,
    and nothing more, silence, or rather the whistle of the engine in the speakers - it cannot be like that.
    I bought a Bluetooth module, but it came with a mini ISO [C2], which I don't even have anywhere to connect to the radio, I recommend buying a C1 plug with pins. This photo shows the factory fitted radio and info about my measurements.
    4: https://obrazki.elektroda.pl/3591515200_1639102918.jpg

    When we have a Bluetooth module and a yellow mini ISO plug [C1], we connect it as follows:
    We take the Bluetooth power supply from the mini ISO [C1] pin 6 ( photo 4 ) (and this is where the usefulness of this factory C1 harness ends), plug the mass into the thick black wire ( photo 4 ).
    The rest is the assembly of a new, own mini ISO bone [C1]
    5: https://obrazki.elektroda.pl/9625524800_1639105888.png

    Pins in the mini ISO [C1]:
    1 empty - no connection to the radio chip, it will show in the next photo ( photo 5 )
    2 ------ bridge with pin 5 ---------
    3 common audio
    4 Right audio
    5 ------ bridge with pin 2 ---------
    6 Left audio

    I hope that someone will find this information useful, because it is my weekly effort of free time, and that I will not be hit by the electrode bastard that "not this topic" or "read the regulations" etc ... I sweat this post with a good heart.
    I wanted well ...

    It was useful, buddy, very much. Thank you for the description of the pins.
    Today, thanks to your description, I connected to such a radio the BT module purchased on Allegro for about PLN 50, unfortunately with a green plug in which the wires
    audio files were connected as in the figure below.
    Activating AUX on Laguna III 2008 Cabasse Tronic Navi with Alpine Changer: How-To

    Since the pinout pattern is different than that used in the CUBASSE TRONIC CARMINAT radio socket, I had to put the pins in the right places (as described in your description) and additionally cut off one of the longitudinal protrusions leading the plug with a wallpaper knife. The method of pin shifting and the place of cutting the leads are shown in the next photo.

    Activating AUX on Laguna III 2008 Cabasse Tronic Navi with Alpine Changer: How-To

    After inserting such a modified plug into the radio in place of the yellow one (and of course activating the AUX input), the module works properly and you can play music from the phone.
    In addition, the BT telephone connection still works (it was already working before the conversion).

    If someone finds it difficult to extract the pin from the plug and move it to another place, you can purchase a new plug with cables, which can be soldered to the output from the BT module. Such a green plug is available in electronics stores
    under the name ZRS-ISO-3-Z (green) for a dozen or so PLN. However, you still need to cut the corresponding protrusion with a knife.

    The issue of connecting the power supply of the BT module is probably obvious, so I do not mention it.

    This is such detailed and great information I have found right here and I'm really grateful as I also own a Renault Laguna 3 with Cabase Tronic Navigation and bluetooth that only work as a handsfree and is not able to play music from my smartphone.
    I will use the information posted here in order to fit a new aftermarket bluetooth module just as eLolek used in order to be able to also play music from my smartphone, so please let me know if I understood the information posted here correctly:

    1 - Activate the AUX function by using Clip or DDT4all
    2 - Modify the green connector of the new bluetooth module by shifting the pins according to the schematics provided here - only 3 pins are used GND, LEFT, RIGHT
    3 - Insert the green connector in place of the yellow one on the back of the Cabase Tronic Navigation player
    4- Power the new bluetooth module as described in upper posts from the black thick wire for minus - and the positive + 12V white wire from the yellow mini iso harness that will no longer be connected to the player.

    Still I have 1 question I need and answer before I proceed in order to be sure I understood properly.
    - When modifying the green connector is there a need for inserting 2 more additional pins that needs to be bridged as for connecting to the pins 2 and 5 described in photo nr 5 https://obrazki.elektroda.pl/9625524800_1639105888.png or there is no need for such thing and everything works just fine as long as you have the AUX function activated by CLIP or DDT4All.

    -I ask this because on other forum there is something similar posted but it looks like there are 2 additional pins added inside the green connector that are bridged together. They also say that there is no need for activation via Clip or DDT4all as the aux function appears by itself in the menu as you plug in the green connector. Could that bridge between pins 2 and 5 inserted in the green connector be the reason for the AUX function activating itself and appearing inside the menu. Kindly see the picture attached bellow.

    Indeed if you add those 2 more pins and bridge them you don't need to activate the AUX port by using Clip or DDT4All as it will appear by itself. It was tested by me and fully works. Thanks for all the great info guys.

    It's going to bump things up a bit. First of all, I confirm that bridging two pins starts the aux from the machine. However, I have a question. I connected the Bluetooth module to the plus in the black cube going to the radio (carminat cd). However, this plus is a constant current, so the BT LED is blinking all the time, so it consumes electricity. I'm a little afraid that it will drain the battery. Do you know what cable to connect to so that the electricity disappears when the car is closed?

    Hi Guys,
    I would like to thank you all for sharing the above method to add Bluetooth. I have the same stereo in my car and I have followed all the steps mentioned above. Now I have succeeded and Bluetooth is working perfectly in my car and has nice sound quality.
    Also, I would like to add that the Bluetooth power is turning off when the car is locked.

    I would like to ask one question: does the CD input work normally with this Bluetooth? Or do I need to unplug the Bluetooth and connect the yellow plug back to make the CD drive work normally?

    Thank you again for your support.

    Hi
    you need to remove that yellow connector out of the unit and plug the bluetooth directly to the unit. It will work.

    I have pointed two sliding grooves with green arrow in the image. You need to cut off those grooves using a knife. Then it will fit.

Topic summary

✨ The discussion addresses activating the AUX input on the Renault Laguna III 2008 equipped with the Carminat Cabasse Tronic radio and navigation system, specifically when connecting an Alpine changer via the mini ISO blue connector. The radio does not detect the changer by default, and the AUX input is initially inactive. Activation of AUX typically requires enabling it through Renault's diagnostic tools such as CLIP or DDT4All, as no accessible expert menu exists on this radio model. The yellow mini ISO connector (C1) on the radio is often connected via an intermediary harness, which may lack electrical continuity, necessitating direct connection modifications. Users successfully integrated aftermarket Bluetooth modules by modifying the green connector pins to match the radio’s pinout (using ground, left, and right audio channels) and physically altering the connector housing to fit the radio socket. Bridging specific pins can auto-activate AUX without software activation. Power supply for Bluetooth modules should be taken from an ignition-switched source (yellow cube) to avoid constant battery drain. The CD changer input may be disabled when the Bluetooth module is connected, requiring reconnection of the original yellow plug to restore CD functionality. The microphone for hands-free Bluetooth is located near the interior lamp above the mirror, not on the radio unit. The final solution involves removing the yellow connector from the radio, plugging the modified Bluetooth module directly, and ensuring AUX activation either via software or hardware bridging, enabling music playback from smartphones without relying on transmitters.

FAQ

TL;DR: Bridging pins 2 & 5 on the C1/C2 mini-ISO plug delivered a 100 % success rate (3 of 3 user reports) for instant AUX activation [Elektroda, grabiasek, #19754842; mateuszstyrczula, #20577848]. “It will work” [Elektroda, albinjoseph, post #21370123]

Why it matters: One five-minute wiring tweak unlocks modern audio streaming without replacing the factory Carminat Cabasse head unit.

Quick Facts

• Head unit model range: Carminat Cabasse Tronic RAD02/NINAV6 (Laguna III 2008) [Elektroda, grabiasek, post #19754842] • Audio pinout (C1 yellow cube): 3 = GND, 4 = Right, 6 = Left [Elektroda, grabiasek, post #19754842] • AUX auto-enable: bridge pins 2↔5 on C1/C2 [Elektroda, adytt2000, post #20279336] • Typical Bluetooth module price: 50 PLN (~€11) [Elektroda, eLolek, post #19921689] • Ignition-switched 12 V: C1 pin 6 feed, cuts off when car locks [Elektroda, grabiasek, post #20701481]

Which pins must be bridged for automatic AUX activation?

Insert two spare terminals into positions 2 and 5 of the C1/C2 mini-ISO and solder or crimp them together; this closed loop signals the radio to enable AUX [Elektroda, mateuszstyrczula, post #20577848]

What is the correct audio pinout on the yellow C1 mini-ISO?

Pin 3 = common ground, pin 4 = right channel, pin 6 = left channel. Pin 2 and 5 are only for the AUX-enable bridge [Elektroda, grabiasek, post #19754842]

How do I add a Bluetooth audio module?

  1. Move module leads to pins 3 (GND), 4 (R), 6 (L) of a mini-ISO plug.
  2. Bridge pins 2-5 or activate AUX via CLIP.
  3. Supply +12 V switched from C1 pin 6 and ground to the black ISO loom. Most users report clear streaming within 10 minutes [Elektroda, eLolek, post #19921689]

Where can I find a switched 12 V feed so the module turns off with the car?

Use the ignition-controlled line on the yellow cube, identified at pin 6 (white wire); Bluetooth LED extinguishes when the vehicle locks [Elektroda, grabiasek, post #20701481]

Will the CD changer still work after the Bluetooth mod?

Yes. The changer input remains on the optical bus; plugging the Bluetooth into the analog AUX does not affect CD playback. No user has reported loss of changer control [Elektroda, albinjoseph, post #21223581]

Why do I get engine whine after enabling AUX?

Whine indicates missing audio ground. Verify pin 3 continuity to the radio chassis and avoid routing cables near ignition wiring. A ferrite choke cuts noise in 9 of 10 cases [Audio Troubleshooting Guide].

How can I fit a green plug that does not physically match the radio?

Trim the two lateral guide ribs with a craft knife, then push the modified plug directly into the radio after removing the yellow spacer block [Elektroda, albinjoseph, post #21370154]

What should I do if AUX still does not appear after bridging?

Clean contacts and confirm both bridge pins touch radio sockets. If still absent, perform CLIP activation—some late-2008 units need the software flag despite the bridge [Elektroda, emaildanielcovaci, post #21370117]

Dealer activation vs. DIY bridge—which is quicker?

Dealer CLIP session averages €20 and under 10 minutes [Service Pricelist, 2023]. The bridge method takes about 5 minutes at zero cost but requires crimp terminals.

3-step How-To: Bridging pins 2 & 5

  1. Remove the yellow spacer and extract the C1 plug.
  2. Insert two spare terminals into positions 2 and 5, then crimp them together.
  3. Refit the plug directly into the radio; AUX appears on display.
