My Z3 has been malfunctioning for the past couple of weeks. Usually in the morning when playing my IPOD, the Z3 will randomly turn up the volume, and skip tracks. I usually just turn it off when it does this. Today, As it rewinded a track I turn it off for 5 min. I turned it back on and the volume started to rise to about 40. I tried to power down the Z3 and the whole unit shut off. It has no power going to it. The buttons are not lit up or nothing. When I got to my destination, I turned off the car, and turned it back on and got NOTHING from the Z3. No power going to it at all...What do you think....Is it fried? Im going to check my cars fuses later today, but I doubt thats it!
