In my previous car I had a Sony MD unit, and the right channel would intermittently drop out. It was a strange fault, since if I cranked up the volume really loud the channel would come back to life... for a few minutes! Knowing I was going to change the car soon I didn't bother checking out if the fault was the head unit or the speakers. However, when I replaced my car I had a Sony CD unit installed and it did exactly the same thing about 2 months after installing it. I just put it down to coincidence and thought it must be a loose connection to the speaker in both cars. However, I had some spare time this weekend so I checked everything out (the unit was now over 12 months old) and the wiring was perfect. Anyway, attracted by the new Sony units front Auxilliary input I thought I'd try replacing this unit with a CDX-GT200. And would you beleive it, it did the same thing... cutting in and out on the right channel! Again it would come back to life if I cranked up the volume, but would drop out again a few minutes later. By now, I was really beginning to think this was my dodgy wiring or a wiring fault in the car. However, not wanting to be defeated, Argos let me take the unit back and swap it for a CDX-GT300. The CDX-GT300 works pefectly and I'm now happy. But goodness me, 3 out of 4 Sony head units demonstrating the same fault is not good at all. I'm absolutely convinced it isn't a wiring fault (after all this happened in 2 different cars!), so I wondered if anyone else has encountered a similar problem with their Sony head unit.
