How do u hook up a USB cord into the radio and my burned cd wont play is there a way to make it work?

Why do you need usb to play the pandora radio app?

It may have a cd stuck in it.

Nothing you can here this was about the time when they introduced producting coding to stop people from making their own CDs ,copyright thing so buy one of them cheap radio transmitter things that plugs into the ciggy lighter and plays a SD card so put your music on this and play through a preset radio station tuned into the sender transmitter

Just plug the cord into the front of the cd player where it says "AUX" and then plug the other end of the cord into the headphone / line out jack on any ipod or mp3 player then select "AUX" instead of CD and the sound will come through the system

If the Cd & USB previously did work, pop Radio faceplate and use paper clip to reset unit

the amp requires a 12 volt power constant, and a 12 volt "on" signal. you prolly have the 12 v "on" hooked up to the car stereo's antennae remote, meaning your amp gets power when the radio is on, cuase the radio is sending a signal to the amp (thinking that it is sending a signal to the antennae to raise)

you do have one of those collapsable antennas, right?

To be working the ipod need to be hook up with the cable cd-1200 (not sold with the avh)and to be plug to the ipod plug on the back of the radio..if you plug the ipod on the usb it wont do..the cable is around 30 $ ..it is the good way to play your ipod ..but if you have a ipod touch 2 generation like i have it wont charge ..if you have any other ipod it will be charging when in use..

if it is new you may have left the screw in the back of the radio you have to takje this screw out for the laser to function it should have a plastic box on it

Most older factory car radios won't play a burned disc. You could try a cd(+ or -) r instead of a rw. But it probably won't work. Some cd players work better with a specific brand of disc too.
Specifications can be found at the radio manufacturers web site.

In 2003 mp3's and burning discs was new to car audio so the radio may not be compatable.

If your truck radio is a factory cd player, the easiest way to play mp3 through it is probably to burn your mp3s to CD as an Audio CD. There are aftermarket car stereos that can play mp3s directly, whether burned straight to CD, on a USB stick or via built-in storage.
