AUX install

Hello guys,

I spent a lot of time on french websites trying to find a solution but can't find nothing that help me.
I want to install AUX cable on my CL203 2005. There is the CDC button and I can switch to AUX mode.
On some models there is a free cable next to the passenger door where we can plug the aux cable. Not on the mine.

I removed the head unit but due to my lack of knowledge in this field, i was not able to find a solution
:



Thank you for your help.

uhg right. All the inputs are optical so no can do (at not without very expensive converter, if it is still available) Sorry that you did all the work to remove the radio for no reason.

Very odd that you cant find an aux input plug. It is not very big, just a simple plastic connector. It may be taped over in the wiring harness running under the passenger door sill trim.
What happens when you press the CDC button for a few seconds? Does it display the aux input?

You used to be able to buy the OEM plug wire/plug that then mounts in the glove compartment. All I did was buy a 3.5mm plug wire and cut/strip and splice. I fished the wire under the carpet and it come up in my armrest tray. I currently use it for a bluetooth adaptor. I play music from my phone via blue tooth now. My daughter mainly drives it now anyway.

Oh men. I already checked the cables next to the passenger door some days ago but I decided to double check and I found a free cable under others that I found the last time.

So this is the pictures of the cables that I found few days ago :




And now, I found this one (but it seems weird because the cable doesn't come from the front of the car but it come from the rear (I am not sure about this statement..)) :




So, this is the good one ? I did't see this one the last time. It's deeper that others.

Thank you for your help.

yep


It comes from the rear because that is where the audio Analog to digital optical module is. Modules like the phone, sat radio etc all enter the MOST fiber optic system in back.

You can buy the adaptor. or just cut strip and connect.

here is the thread you want to look at
