Ulix, and anyone else wanting a modern radio in a pos earth car! Get a 
12V relay from Radio Shack, or wherever, and have it activated by the 
ignition switch. Run the + lead that operates the radio and 
display through the relay's normally open contacts to earth. Run the 
other + lead (for the memory and clock) directly to earth, and the - lead 
to unswitched - (fuse protected, of course).
