E39 Factory Radio Dying???

[Guelphguy]

Noticed a few weeks ago on my 2003 530i that my factory stereo has started acting very odd? I had 6 CD's loaded in the CD changer and now it only see's 1, 5 and 6. Then a few days ago...suddenly only very local radio stations come in? I am in Cambridge and could always get Toronto stations, now NO Toronto stations will come in, only the local KW ones?
Is my head unit on it's way out?

Thanks,

I think I have my answer? This morning I could only switch between the CD changer and AM....would not let me select FM...although after parking the car for awhile, then FM did work....so I assume that my Head Unit is on its way out.
