I have a 2003 mercedes ml 350 I need to type in security code but I cant type the code in because it says wait

  • When you get a message that says "wait" it is because the wrong code was entered incorrectly. Each time the word "wait" appears the wait is a little longer. The radio must be on during this "wait" time. When it goes away then enter the code correctly and you will have no problems.

  • Hope this helps.
