This morning i was cleaning my dvd nav system,i was watching a dvd, so i remove the key from the ignition, close it down, i accidentally hit the nav on button, and the dvd continued to play without the key in the ignition, my question is, is that normal, because i was watching a movie without a key in the ignition,


Try it and let me know.

Should be described in your manual.

This has been discussed. The radio will play for 30 minutes without a key, which includes DVD player.

That is normal. MB radios have always been able to be turned on without the key. On the new 204 though it has controls that will not let the battery go dead. This feature is on a couple other models 221 and so on. Basically if you have the command running and battery voltage gets low there will be a warning that shows saying start engine or command will shut down. This works for everything in the car. So ideally your battery will always have enough power to start the car.

If the key isn't in the ignition mine shuts off after 2 minutes. A warning message comes up to insert the key a bit before the time is up.

I had no clue about this, and i consider myself a very smart car guy.

My 1989 300E did the same thing. You can turn on the radio w/o the key in the ignition.

When I remove the key the radio/dvd turns off and screen folds away. Key in ignition radio/dvd will carry on playing for 30 minutes.
