    HU doesnt keep settings

    so i bought a pioneer 6800 hu, sounds great but....whenever i turn the car off and back on it does not keep the settings, it starts back up in demo mode like it was just turned on the first time. it doesnt save the eq, time, spot where cd last played, or anything. the harness from my car hass a yellow batt/memory cord but theres no spot to plug it in on the hu (there was on my old 1) im guessing it would go along with the power and acc wire but that would probally be bad if im wronge. theres 2 wires from the head unit not in use a orange lighting switch terminal wire and a yellow/black mute wire my car has a orange illimination wire witch wasnt hooked up to the old hu either so i decided not to use it

    another weird thing....my abs light used to be on...witch is probally bad....but since the new hu...it has gone away

    Re: HU doesnt keep settings

    because the yellow wire from the deck takes a constant 12 volts. and that is what keeps the mem.
