Hi there. I have a defender 90 and put in another Land rover radio. I have the code, but got new battery and typed in the wrong code by accident. Now it just shows the wrong code and I know there is a way to reset to be able to put in code again. But can't seem to figure it out..... HELP.. Thanks.

 

On my P38 if you ignore it for something like 20 or thirty minutes it will let you put in the correct code.

 

In a D1 (very similar to D90) there seems to be a requirement that you have the key in pos II for 90+ minutes (the truck can be running or not but Pos II is essential). After that the code should work.

 

i am pretty sure if you just pull the battery negative terminal connection again it will go back to code and you can re-enter
