406 Radio

Have got a 406 LX (2000) with a Clarion radio installed (front loading CD)..
It has been working fine for ages but this morning it suddenly went berserk,
Firstly the radio switched itself off then after a minute back on again, the
volume shot up to full blast and almost made me crash, station went dead
then it started beeping every few seconds, showing "MUTE" on the display and
randomly switching off whilst listening to stations. It locked on one
station and wouldnt let me select a different one. Coming home this evening
the car behaved beautifully, would the radio be showing signs of failing of
would it have been something else?

 

I'm pretty sure in that car, the radio is controlled remotely by the
display, and all presses on the radio's front panel are simply transmitted
to the display, which would explain how it can ignore you. So what you
experienced is simply a software fault. An ignition cycle usually cures it
(turn ignition off, wait for the ignition relay click a few minutes later,
turn ignition on).
