I have the problem with my RX65 I bought it 4 months ago, it
worked perfectly but suddenly one day after switching it on,
my RX65 got silent. Radar detection works Ok, but only the visual
alert, without any beeping. Volume adjusting, switching AutoMute
and reseting didn't help, it remains silent.
Could you give any advices, other than returning RX65 back to the dealer?
