I have a 2001 300m that the radio does not seem to work anymore.....Originally I thought it had to do something with how hot it got in the car because in the morning the radio seemed to work. Now the radio does not seem to work at all. The lights come on but there is no sound and the preset channels can not be changed. The EQ blinks all the time now, even when the car is shut off. The display does come on. The first few times that the radio first started to act up , the low fuel light would come on and make a bing sound. This has stopped. Has anyone else had this problem or help me diagnose? This is a lease and I do not want to dump any money into this car since the lease is almost up.

Thanks
