Hello, my name is***** and i will do my best to assist you.I am going over your story now and will reply back soon with some info,thanks!

Expert:  Lou P. master tech replied 9 days ago.

where did you get the code from that you entered and also If you give me your vin i can get you the last code stored in the mercedes system, if that does not work we will have to remove the radio and get the serial number off the side of the radio, sometimes even we would write the code on the case of the radio. so get me the vin and i can get you the code, :)

thanks, ***** *****

oh ok

Expert:  Lou P. master tech replied 9 days ago.

that is not a problem, here is how to fix it. i am typing now

Expert:  Lou P. master tech replied 9 days ago.

when the radio says WAIT it is because the wrong code was entered 3 times, there are 3 levels of WAIT time,

  1. 15 minutes
  2. 1 hour
  3. up to 24 hours

so in order to get the radio back to CODE you must leave the radio on and the ignition on until the radio goes back to CODE, so your best bet is to set a battery charger on the battery and leave the key on and the radio on to display WAIT until it goes back to CODE . it will come off it just takes time. each time the power is turned off it resets the timer. hope this helps.
