My battery went dead and I charged it and now my radio won't turn on without the code and I don't remember where I put it. Will any mercedes code get it to work again?

 

you will need to pull the unit and get numbers off it and call a dealer to get the codes. you may need to get a couple of keys to remove it. there is a small slot on each side of the radio if you need these removal tools.. In my case I had a number in my cars paperwork but was the wrong code for my unit.

 

i had the same problem called the 800 number and gave the vin # they told me the code via telephone

 

call the 800# with your vin # theyll tellyou the code

 

What is the 800 #
