Re: Head Unit problem

Go to and search out the user manual. Most of these units have a reset button for just these types of issues. The reset button is usually behind a tiny hole that you need to insert a paper clip into. You can also try disconnecting tthe ground from the car battery and reconnecting it. That could cause the radio to reset.

My iphone asks for a four digit code to pair as a bluetooth device with my sony xplod, how do i enter the 4 digit code into my sony xplod?

You enter a code on the source device, enter the code again on the head unit (using the remote control is the easiest way to do so), and the two devices connect.

Im not sure about power wire red black ground and yellow not sure?

Connect black to earth or battery negative.
Connect red to battery positive or the acc lead from your ignition switch. If connected to acc the unit will power down when the vehicle is switched off. If connected to battery positive it will remain on irrespective of ignition switch position.
Connect yellow to battery positive for memory power. The moment this lead loses power all the settings/memory on the unit will be lost.

No power to front panel but have power to main unit.

You Have constant power (yellow wire) but your Acc wire or switched power wire (RED WIRE) does not have power. Check the connection of this wire. You most likely have a blown fuse in your vehicles fuse panel.

I need a color code for a Sony Xplod CDX-GT23W.

Guessing that you don't still have the owners/install manual.

On the back of the head unit there should be a group of unused/unconnected wires (with any luck they will be marked), one or more might be an amp turn-on or power antenna lead, so I suggest (with the unit turned on) testing each wire with a DC voltage tester so as to identify and separate any leads supplying 12+ volts. the remaining group will consist of speaker leads. Trial and error testing will determine the proper L & R rear speaker leads.

Good luck

Switch your blue wires around.

You have put the remote antenna wire to the remote turn on of the amplifier. The radio cuts off the power to the "power antenna" when you switch to a different mode... so your amplifier is now losing the turn on signal it requires to stay on.

Simple 2 minute fix.

Thanks for using FixYa - a FixYa rating is appreciated!!
