HU not working correctly

i'm quite new at this too but after prepping myself for my first install and reading heaps of articles, i bet you could use your remote wire to trigger your power antenna.

what type of vehicle is this???

Use a volt meter to find your constant power and your ignition on power.  It's not good to have them both to constant, you'll leave the radio on on day and come back with a dead battery.  The remote wire is usually some type of blue wire.  Hope that helps.

i already tried using remote trigger to power antenna....doesnt work...if i put power antenna to ignition itll work though. this is on a 1997 acura integra...i already printed out the wiring schematic but it doesnt seem to help any. i wired ignition and constant together but it doesnt stay on without the key in and ignition on...so im assuming i no longer have constant....maybe a torn wire? remote wire is usually a blue wire? i know its a blue wire coming from the head unit but is it going to be a blue wire coming from the car? thanks.Thuan

For a professional to fix that it would take 10 min, , but for us to explain it to you its going to take days.  You should check out some prices at a local shop, help support the economy2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

Thuan, If you have power with the key in the ignition that is your remote wire. Connect that wire to the red wire on the head unit. If you don't have a constant power wire most likely it's shorted out. Check both of the fuse box inside and underneath the hood. If I understand you correctly, your car is a 1997 Interga. The constant power wire for your car is blue/white or yellow/red. Fine and replace the fauty fuse that was shorted out. Once you get a constant wire you can now connect this wire to the yellow wire on the head unit.    “if i put power antenna to ignition itll work though”. This wire that you mention. Connect this to the blue wire on the head unit. Before you do this, used a digital meter and see if you are getting a 12 volt on the blue wire when the head unit power up. If not, you have a problem. One of them is the head unit is defective; the other one is that you shorted it out. Depending on the type of head unit you have, some will reset itself other you will need to bring it back to get it service. Use a digital meter and match the head unit wire up to this.Be careful whose advice you buy, but be patient with those who supply it.

hey thanks for the advice...finally got it to work. Thuan
