Built in stereo on Renault Espace:
 

I recently bought a Renault Grand Espace (51 reg 2001). The problem is
that the guy who sold it to me bought a new remote control for the
built in stereo to replace a lost one. It does not work however. I
presume the stereo has to be taught some how that this is the new
remote ( like you do with a new t.v remote). Does anyone have any idea
how to resolve this problem?
