mine used to give me problems: stay on when the ignition was off, flash on and off when driving, but it's been good lately. i have a sony xplode, and its either the unit or my car. i dont know, mazdas and electricity dont mix. they need to recruit more EE's and less ME's (although keeps the ME's that are pro wankle!)

Good luck with it, I have checked and rechecked all my wiring, and I cant figure out why my power antenna goes down when I turn my lights on.
