Customer Question

I have a Mercedes R350. All controls on my radio becomes inoperable but will start functioning after driving 15 to 30 minutes. If you leave the radio in the on position when shutting the car off, when you restart the car the radio will play on the station you left it on but you cannot change stations for 15 to 30 minutes again.
