Hi

Does anyone know how I can reset the radio for the ML 320? Here is the problem that I'm having.

Two days ago I took out the Navigation CD and put in a music CD to listen. I was able to listen to music and everything is fine. Until I took out the music CD, it seems that the radio didn't notice that I took out the CD and it froze at the CD screen. Now I can't even get the navigation to work. Are there tricks that I press certain buttons to reset the radio?

The only way I can think about resetting is unplugging the battery from the car.

What is also weird is now I'm able to turn on the radio at anytime even when there is no key in the ignation.

Please Advice.

Thanks.
