2nd time this has happened to me now and from memory both times it was raining (not sure why that should have anything to do with it)..
Pretty much turn the car on, stereo starts up as per usual then a few seconds later all the sounds goes off. the stereo doesn't respond to any button pushes etc. the bluetooth audio buttons no longer work. nor does the speech on the gps.
Turn the power off on the car.. turn it back on and the stero works fine again for about 10 seconds. rinse and repeat.
no error is shown visually. and i can still insert/remove cd's. car is stock standard luxury model & 1 month old.
any ideas? or it's on the phone to mazda for me??
