7 inch dual touch screen locked?!?!?!

Question

I have a XDVD8181 that has somehow locked its self. I don't remember putting a code in but when i moved it from one car to the other, it locked its self. is there a reset button to push or a combination of buttons to push to reset it? I don't have the box or receipt for it anymore so i don't think the factory will help me much. plus i work all the hours that the tech line is open so i don't have an opportunity to call them. I was hoping that someone has had this same problem and could tell me how they got it unlocked. if you have any ideas or know how to do it, please let me know. Thank you for any help.

Answer 1

The default anti-theft code is 0000. However the default setting is OFF. So if it has locked someone has more than likely programed a code into it.

You can call Dual at 1-800-382-5476.

The user manual for your unit can be located at the reference link below.  

Answer 2

Well you can try a few universal codes that I have used.. Depending on if its a four digit code or not. Try 0000 or 1234 and push enter after you try each one.
