I just bought a brand new Mazda 3 and i am having some problmes with the auto system anyone have any ideas?

Question

It seems that the volume goes up and down with out anyone pressing any buttons. It turns the bass up and down and on and off and sometimes, the sound does not even reach to the back where the other passangers are. Please anyone with information I would greatly appreciate it.

Click on the unstable audio link (it is the first one).  Check your vehicle VIN number to the ones listed.  Apparently there is a glitch in the head unit of 2008/2008.5 mazda 3's.  You will need to take it back to the dealer so that they can order and replace the defective head unit.
