I have a Mirage from 2013, lately my multimedia system (not the one with the touch screen), is not working correctly,
whenever I try to volume up with the steering button the volume goes down and up, seems that its randomly.
Since last week, my buttons for moving to next or backward tracks not working well. the backward buttons sometimes do the backward function, and sometimes does the forward funtion...!

Is anyone know if I can fix it manually by myself or should I take the car to my garage.
