How do i set the clock on a 2004 mercedes slk230?

no year told (omg even 1996 to 2020 and are NOT THE SAME)
nor the words Mercedes-Benz SLK230
no country told, and car are not the same all over the world
sad no.
fuses blown or CB circuit breakers tripped

I'm assuming yours has the digital clock. I think on the 2004 you can set the clock through the function display behind the steering wheel. Try this video. It is for a 2003 model so yours should be the same.

Radio code is specific for each and every car. It is specific like anti theft code.

You can get it by providing your VIN# and registration details in authorized dealership. Nobody else can provide you. If anybody can provide you that , then there is no meaning of security for your car.

If you have an owners manual, look in it, it will show how to set the clock. ( usually manual is in the glove box).

The clock has to be set through the comand unit/radio. Push the SERV button on the comand, then go to SETTINGS, then TIME AND DATE. and set the time and date, *note* you will probably have to drive the car to pick up sattilites. and gps position.
