1999 Ford Falcon 6 cyl Two Wheel Drive Automatic 152000 miles
I have a Ford Falcon 1999. I intended to install a new CD, radio system, so I pulled the old radio system out and disconnected all wires. But after that, I found that I can not replace it because I could not plug the original wire in to the new system. Therefore, I put the old system back in. However, when I connected it again, it always show " ERR" on the small radio screen. I disconnected the battery for 1 hour, connected battery again but the radio still show " ERR". It did not give me any chance to input the CODE. Is there any thing wrong with the radio? The car computer system or the wire to radio? Please help.
