Citroen C5 radio wont turn on

[Azur98]

Hello guys, as in the title my radio suddenly stopped working. I can connect via bluetooth and take calls but thats it. I was at a citroen shop and they tested everything and said that the power delivery and everything else was fine and that the radio is ok, but the radio wont turn on.
Did someone have similar problems?

You haven't said which C5 you have - I'm assuming an X7 MK III from 2008 on? ALso what Audio system do you have? RD4 with Hands free, RD45, MyWay (RNEG), eMyWay (RT6), Navidrive 3D (NG4), SMEG etc etc.....?

If you're not sure, stick your VIN up here (automatically masked on sibmission) and I can look it up.

Sorry i was in a hurry, yes the radio is RD4 with hands free from Bosch both the old one and the one that i bought later. The Car is an MK III 2010.
Thanks for the reply.

Ok, so is the screen displaying anything or is that blank? The Multifunction 'C' Display Screens on these units have an ECU itself that does the configuration for the Head Unit - so that's the reason I'm asking if there is anything on the display.

A Diagnostic with Diagbox is probably going to be needed to determine what the problem is - as that can provide live data on the buttons - so you can see if the head unit is receiving signals from the buttons. It should also bring up an error codes.

Try the BSI Reset / Battery Disconnect / Reconnect Procedure first of all and make sure you follow the timings properly and DON'T open any doors whilst waiting for the time to pass - otherwise it will wake up the ECUs again and the whole procedure will have to be repeated. It's free and doesn't cost anything to try this in case there is a glitch in the ECU - especially if the battery has been disconnected recently or run low on power.

The little screen above the radio is working, and i can access the settings from my steering wheel like changig the date and bluetooth settings. I was at a Citroen dealer and they've said that they used their diagnostic tools and that everything should be working because it didn't found any problem.
Im going to try that reset method.

Yes, the BSi reset can clear glitches (in the same way that a reboot of a PC can clear them), but if there is an actual problem it won't clear that (saying that, the fact that Citroen with their diagnostics did not find a problem is good news). Do make sure to follow the procedure properly, as it does allow the various ECUs to shut down properly and then to boot back up cleanly.

Well i've did the reset and the clock is now set to january 2007 so i think the reset did its job but it still wont power on. I also found out that i have mice under the bonnet so im guessing he must have eaten some wires

That is a possibility!

[Azur98]

But now that im thinking i've had the problem before the rats because i've opened the bonnet and there was no sign of them. But thanks for the help guys im going to the dealer soon again so they can find the issue.

Hey guys, my radio work i just had to hit it hard enough

[Azur98]

It works now sort of i cant switch to bluetooth or aux with the source button. I can still connect my phone via bluetooth but unfortunately i cant play any music. Any idea what to do guys?

Another thump?

I think you may have a loose connection possibly, so check the pins and wiring in the blocks.
