I was installing it and when I pushed it into the dash with pressure along the edges, the face went dead. I have sent it to a repair place that HBChris uses and they told me the faceplate has to be replaced and it is a common problem. I have been able to find every part but not the faceplate, repair shop is having the same issue. I know Rover uses the same radio, dead end there too.
I'll search my Rondels to see if I can find the add you refer to.
This radio is a nice upgrade for an e24 or e28. Want to use it in my M6 which still has the factory cassette
