My radio in my ML320 stays on when I turn off the ignition. do you have any hints on what could be wrong?

The same thing just happened to me after replacing the car battery. Everything works fine except the radio doesn't turn off when I remove the key.

It's a fuse. But not the radio fuse. It's the fuse for the overhead trip computer. It's fuse # 10 on the '98 ML320.

Having the same problem in a '98 ML320. Any idea as to why fuse 10 is blowing?

Have disconnected the auxiliary power outlets, the illuminated mirrors on the sunvisors, the optional M-B GPS unit and the radio off but fuse 10 blows the moment the ignition switch is turned to on.

Anyone else having this problem? Faulty ignition switch?
