On my 750 lately the radio goes off and the DSC light comes on. Few secounds later all is back to normal. Today was the exception. Lost the radio and all the settings. Steering wheel didn't go up as usual when I exit the car but the alarm kicked in when I set it. Came back 10 minutes later car started fine but I had to reset the date and time. Still no radio and cd player. Did this one more time and finally the radio came back on. Anyone know what could be causing this?

Thanks,

Tony
