In update manu, shows 2 options. SW update is looking for CD, I guess it is for command software like bluetooth driver, CDDB database etc.

Any chance it has to do with the car's engine, transmission, etc?

Kind of hard to explain in a post. Basically you put one finger on both top buttons and do the same for the bottom set. Your finger will have the gap that is between the buttons in the middle of the tip. Does this make sense? I know if you would see someone do it you would understand right away. I can only do this for the windows down BTW can't do it for up.

you can actually click the buttons fully and the windows would roll up or down without you holding the buttons up or down.

This is not really a secret then. (28- if you use two fingers you can do all fore windows at the same time, up or down.)

In the W203, bringing up the engineering menu also allowed you to read the exact oil level in the sump. Does this wok on the W204. (Don't have mine yet :-) )

No Jack, not on mine anyway ( 220CDI) .I just have to use the true ,tried & reliable old dip stick under the bonnet method once a month.
By the way, my engine used a litre of oil in the first 5000 km , I changed the oil & no visable decline in the next 4000 KM. John.

This secrets thread is really good!

BE VERY CAREFUL IN THE ENGINEERING MODE! If you make adjustments in the Parametric EQ- you cannot manually restore the factory settings.
Example: Filter 2 factory setting was at 2300. When you adjust it- the values are in intervals of 500 (2000, 2500, 3000). You are unable to select 2300.
I recommend that unless you know what you are doing-DON'T MESS AROUND!

what kind of phone.

aprince2die4

nokia 6301

I wonder if its phone specific or if your cars just magical ;P

I should be getting my 2009 C300 today or tomorow, I'll test it with my Nokia N95.

aprince2die4

i know i thought it was weird too and i even covered the speaker on the phone and turned the volume knob on the car up and down and it was indeed coming from the car speakers

I had a Nokia N82 and it does the same thing too. Also you can send the contacts all at once as well. good job Nokia. But my girlfriend jacked my phone so now I am using Sony ericsson C902. This fone does not do what nokia can. In addition I have the ring volume problem where even if I could turn down the ring volume when incoming calls came, the car would resets back to the ring default volume. which is quite LOUD. Its hurting my ear and kind of hazardous as well. So anyone with a secret code that can turn the volume down and set it in memory?
