Help Please?

Hi all, just purchased a 2001 ML320, my first Benz experience and I'm frustrated.

The radio/nav screen is stuck in 'wait' mode... I've contacted the seller, I have the little gray credit-card size card identifying the Radio Code. I have the manuals and have read them.

When the screen says 'Enter code' - I enter the code using the numeric pad... and then it appears I should push the button at the bottom under the screen where it says 'OK'

I push that button and it erases my input... I enter the code again, do the same thing... it erases my input... one more time and I'm locked out for an hour.

Do I have a bad code? How can I check? Is there something else I do besides punch in the code and push the 'ok' button?

Thanks for any help - it's a wonderful vehicle, but it would be better if I could use more of the features!

RE: Help Please?

the mcs unit was replaced at on time, and the radio card was never replaced with the proper code. at this point, the only way to get the code, is to removed the radio, (special tools needed) retrieve the units serial number, and run it through mercedes VMI system. (only at a dealer) that will give you the radios proper code.
