Alpine indash reciever 1004

i believe if you dont have the parking brake hooked up on your unit, you wont be able to watch any thing. check around online or your local audio dealer bout buying a bypass relay so you can drive and watch if you choose to. or hook that wire up right. hope this was helpfull

The Zune is not compatible with your head unit.

you need to hook up the foot brake like it said but hook up a switch on the parking brake wire to ground do not hook it up to parking brake just a switch ground one side ant togle it while your foot is on the brake once the screen is on leave the switch in that position you will have to do this every time you turn the car off but you can see the screen while driving

from page 6 of the DVI-9990 Owner's manual

u need to switch function screen to dvd screen. Button is on front of unit to scroll through screens.

Many aftermarket car stereo has to output trigger wires, one antenna and one amplifier. Antenna trigger only works in radio mode for the power antenna to operate. Amplifier wire operates in any mode the stereo is in. Check to make sure you hooked up the correct blue wire to your amplifer.

did you hook up the video cable? and did you follow the brake sequence if so you have a bad unit

move all power lines away from unit and connect all grounds to same spot

it isn't bypassed properly. recheck bypass wiring.

lol i had the exact problem that you are having with my alpine. The solution is taking the blue cord that was inside the vehicle (forgot what cord it was) and actually connecting it with the other blue cord thats different makes the factory amp read the cd player and ta-da it works. crazy isn't it
