• If you press power button (1), does anything happens?
• If you press mute button (2), does anything happens?
• If you scroll up or down (4), does anything happens?

- You can try resetting/rebooting radio by pressing eject button (3) for 5-10 seconds and see if it does anything for you.

 

I have tried 1 2 & 4 but nothing happens i will try 3 tomm i will tell you how I get on .thanks

 

Alternate scenario...
If there is a blown speaker anywhere, i think the system shuts itself down. Parking sensors will still work.

 

Ops... Eject button (3) is on the left to the CD slot. What I marked on the picture is screen off button.
I have edited my previous post.

 

Ok thanks for the advice i will investigate tonight once in from work .

 

Also.my peugeot is a 508 sw estate 2012 !! 1.6 hdi

 

My radio all working now thank you for advice

 

How did you fix it?

 

I did the bsi reset procedure and it started woorking .

 

If the screen doesn't come on, it could be a corrupted sd card containing the files for the firmware. You would need to clone the data to a new sd card to use on the head unit or try formatting the same sd card after you've made the backup of it and reinstalling the files back on the sdcard. The files can get corrupted due to bad sectors in which case you need to clone to a new sdcard.

 

Having no sound from the speaker on a RT6 could be because of open circuit to the the speaker's voice coil or high resistance due to a corroded tract. You can easily diagnose with Diagbox the fault for the head unit or amplifier and get the code and description for a solution.

If there is an open circuit or high resistance to the voice coil, just solder an external wire from the connector leads of the speaker connector to the voice coil. You can manually measure continuity to check for the connection of each speaker if you have a multimeter but Diagbox makes the guessing work easy.
