My FM reception has become worse, picking up only the strongest of signals. I've looked for bad grounds, broken wires to the amplifiers and cleaned all the terminals in the rear spoiler. Next thing maybe to replace the rear FM amplifier but I'd be guessing. If I ignore the FM problem, has anybody used the Denison DAB+R tuner?
