Hi,
I have just had to replace the battery in my Renault Laguna RT 1.8 and need to re-enter the code for my Renault/Pioneer CD/radio. I have the code and remember that I use the first 4 preset channel buttons to cycle through and set each number of the 4 digit code in turn. However, after I have setup the number I can't get it to accept the entered code. Any clues greatfully accepted.
