Hi there i have a mazda 6 1800 cc witch i bought on 2007. the cd player is locked.now there is a message err on the panel do gou know how i can unlock this? thanks a lot stelios peratinos

You input the anti theft code that cam with the car.

Try gumtree.com

People on ebay can get the code for 99p just need the serial number for the unit. Ive used these people before worth 99p

when the live is disconnected the stereo locks itself to unlock it you need the code which is usually a four digit number code look if its in the cars hand books if not a mazda main dealer will be able to get the code for you or i use a local radio code man than charges £10 so depending on how much it costs from a mazda dealer you may be as well buying a second hand cd player and putting that in

Is there a CD inside the CD player? You could try pulling the fuse for the radio (look at the fuse box panel for the exact fuse) and leave it out for 10 secs, then turn the car to the on position and leave for 20-30 secs.. turn the car off and put the fuse back in and then turn the car on and if you;re lucky, the radio will reset... This works for Volkswagens and since Audi is the same company, it should work

My CD Player did the same. It showed an "ERR" message when trying to detect the beginning of a CD. I thought that the CD was dirty and wiped it down. Then I discovered that the player would detect the CD when the car was idle, but not when the car was in motion. Maybe the laser is THAT sensitive. Hope this works for you.

dear friend- the error code means the lazer is not reading your cd,if it is a pirate cd it might be the problem,or the lens must be cleaned.

HI,THE REASON YOU ARE GETTING AN ERROR MESSAGE IS BECAUSE THE MECHANISM IS FAULTY,YOU WILL HAVE TO HAVE IT REPAIRED,ANDY

This is not a fuse problem, it may be a dirty laser lens or a broken loading mechanism, buy a CD player cleaner disk, if that won't work you will have to pull the unit out and send it in for repair at an authorized GM electronics repair station.

When you bought the car your dealer must have given you that code or you can call them and let them know your registeration details they will give u the code for free all you have to do is to give them your details.
Good Luck !!!!!!!!!!!!!!!!!!!
