My B-I-L has an '09 'rolla. I heard through my sister that he is having trouble with the radio. I'm not positive what the exact malfunction is, but apparently it's intermittent. The car is under warranty so he's had it back to the dealer several times, but they just keep saying they can't duplicate the problem and won't replace the radio. I'm not asking anyone here to diagnose it with no info, I'd just like to hear if there are any known common issues with the radios in '09 that he can use as ammo the next time he goes to the dealer. TIA.
