I want to know if it is possible to repair it?
I just open it, i do not see anything.
Do you know, where the breakdown comes?
I will send some pictures if i begin the repair

Hi, anachonda.
What kind of problem are you experiencing?
Is it the noise from the speaker?
If that is the case, then you may have problem with your Bose Amplifier (located inside the speaker box at the doors and at the passenger foot well) and not the OEM radio (head unit).
More information would help us in supporting you.

Hi Kaz,
All my amps are new, it's the radio!
I haven't lights, sounds. Nothing.
And the fuse is ok.
Was your head unit working fine until recently and suddenly failed?
Or, never worked since the start of your ownership?
At the time of failure, any possibility of cable being disconnected/disturbed by other modifications that you were working on?
No lights at all....
On your head unit, you should have the following pin out information.
If you have the bench power supply, you can apply 12V at the pin 'ACC (+)' and 'GROUND' (-).
Your head unit will operate on the bench even without the power at the pin 'BATTERY'.
'ILLUMI+' is for the illumination control unit and 'SWD+B' is for the power aerial as well as for switching On/Off the power supply to the Bose amplifier but for this bench test, they are not required.
This will confirm whether you have wiring issue on the chassis side or indeed, a failure at your head unit.
If it is my head unit, I'll be happy spending hours to check the power circuit first and then move on to each modules.
You may want to try your local Alpine car audio place for a quote on repair. In Japan, it was not too expensive long-long time ago for replacing some of the power capaciotrs but this all depends on what kind of failure you have with your head unit.
I don't know the radio frequency range used in France but you may find it more cost effective to seek the used head unit on the auction site.

SUDDENLY
I haven't modifications on the harness. The "allume cigare (in french)" is working.
No lights at all.
I have a collegue that is working on electronics, i will ask monday if he can find the problem.
I think it's the big capacitors, i'll give you the news like possible.
Hi Kaz,
It does not work on the bench with the power supply.
We will remove the boards of the frame to inspect all the components tomorrow.
My collegue thinks it's the IC at the middle of the upper board. the big IC.
You changed it on your pictures?
I will put some pictures of the check-up.
Bye,
Greg
