I don't know if this is the correct place to put this post but here goes.
The Citroen C4 Picasso I have was first registered in OCT 2013 and has been fine until now.
The VIN is VF7**************[VIN obfuscated, can be read by forum staff]
A month ago the 7" touchscreen that controls the climate, radio, phone and diagnostics etc. Just went blank and as there is no other way to control anything it is stuck with the AC on cold at present.
I took it to the repair company I use regularly only for him to tell me it wasn't the fuses or anything so he had it sent to BBA REMAN for tests and they said the screen works. Now I was told it was maybe the firmware needs upgrading so my car was taken to Windsors Citroen of Wallasey who tried this upgrade but it didn't work. They have now tested it and said its the amplifier that needs replacing and it will cost about £600 with fitting, programming and VAT.
I do have an extended warranty but it seems to cover nothing up to now. I've been told that media is not covered, but to me it is not the media.
Here's hoping you can help . A very appreciative ( but not happy ) Gray K
