I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

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

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.

I've got an Alpine CVA1004 and use my ipod on the aux input of the headunit. The alpine-ipod interface was too confusing for me, with the ipod connected to the aux input, I just control the music from the Ipod, I find it easier that way.

Doing so is very dangerous.
I admit it is an annoyance because some basic features you can't even control while driving.
Once again I would really suggest not bypassing the saftey feature.
If you still wan't to go threw with it there's 2 different ways. One of which is applying the e-brake ever so slightly so that the brake light comes on on your dash but could also wear out your e-brake over time doing this. The other is permanently grounding the e-brake wire that comes from the cva-1004. You must cut the wire and ground it (on the cva-1004 side of the cut wire) and insulate the other side of the wire you cut so that it dosen't interfere with the normal operation of the brake light.

Rember..... When you have an accident you were warned!

I think you are using an external amplifier,if this is the case,you may be using the wrong remote wire for the amp.
Alpine use two blue wires,BLUE (only) this wire is for the pwr antenna and every time you insert a cd, this pwr line cut out.
BLUE/WHITE STRIPE this is the remote wire that you need to connect the remote of the amplifier.

thanks for rating

make sure the handbrake wire is attached to a gd ground or it won,t allow you into the menu because it thinks its unsafe while the ignition is turned on !

its a yellow/blue striped wire that needs to be earthed !

im having the same problem with my amp, I took it to best buy and they said the amp was recieving power and recieving signals from the deck and i had everything hooked up right but that in the circuit board all the connections were blown, meaning i have a blown amp, i hope this isnt your problem but it definetly sounds like it. GOODLUCK

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
