A strange thing.  A strong station will from time to time go instantly
to pure static.  Sometimes for a few seconds, sometimes for a few
minutes.  Hitting scan will usually bring it to perhaps 1 or 2 other
stations.  When the station comes back, it does so in the same way
that it left, instantly.  The curious thing is that if you turn the
engine off while this is going on, the static goes away totally and
the station returns.  The dealership thinks that the radio is going
but it seems to me that there might be some kind of electrical
interference going on.  Any thoughts?

Thanks very much,
