I have a Mazda 2 Tamara, 2009. Recently I have had issues with my radio turning off when going over bumps. This causes my “room” fuse to blow, I changed the fuse and today it has done it again. Is it a short? Or loose connection at the back of the stereo? I have the standard Mazda stereo so I no it’s a mission to access the back of it. I took it into my local Mazda dealership and they said it “could” be my ECU but I’m having no other issues and that “it might not fix the problem” so I said don’t worry about it.

any ideas?
