My 92 Senator used to have this. :-? Easier to set too. 
Radio was the only decent thing in that car. Actually, the only part that didn't rust either 
& I thought you were going to say that the FM siganl failed on your
???4780! 
I still say that my 24v Senator would beat my Omega hands/tyres down over all. :-?
At least i can now get in my omega with out using both hands on the door handle.
Tunnie and I proved that a 3.0 Omega auto is quicker than a 24v senny.... ....its was teh poor power delivery on 24v that made it seem faster.
The figures for the two cars say than an Omega is quicker, but I still think the Senator was a better all round car! So, ner ner ne ner ner! 
Obviously we know the standard Omega has the legs on a standard Senator. But the Omega's ride quality is better, handling better, lower noise (wind/road).
Well I have owned a 3.0 24v Omega & Senny.... (Omega does not have the multi-rams working yet!)
The problem is the Senator
feels faster, i think it sounds nicer too.
The 4k Rpm launcher puts a big smile on your face, where as the delivery is much smoother (and less fun) in the V6.
The V6 is smoother though.... but not quite so good on the juice as the S6 i found.
Currently averaging 22mpg in the V6
