I just had a xm direct tuner box hooked up to my sony aftermarket head unit..and once I set the sounds the way i like (bass ...treble sub..ect) it sounds great. But whenever I turn the car off or switch from xm to radio or to cd player it automatically resets to factory setting. Is is a wiring problem or are all sony direct tuners this way?

 

Whoever installed it didn't conect the constent power wire (yellow, Memory Lead), or you have a blown fuse. Bring it back to whoever put it in.
