Citroen Berlingo multi-space Forte
 

I have a Citroen Berlingo Multispace 1.6 Forte
I have tried to change the radio to a a sony.With the sony fitted the
Multifuncion panel/Clock goes haywire .It reports all kinds of
problems ie doors open when not.Is there an answer to this or
must i stay with the radio as fitted,then everything works as it should.
Thanks in advance for any answers.
