Thread: Engineering Menu in Comand APS ON MERCEDES CARS

A couple of information about this mode:
It can be activate on 203's Comand by presssing at the same time and holding down for some seconds Mute +Phone Down+Serv.
On W211 the sequence is Mute + Eject + midle right softbutton
on some other units different combination may work. Try:
- MUTE + 3 + 4 +5
- Phone Down + 1 + 3 + 6
- 1+6+4+3
- mute + phone down + serv
- mute + 3 +4 +6
- mute+357
There are a lot of things you can do.
1 for all:
Go to Diagnose
Scroll down to find "Set Variant"
select the last one: (it is a Smart)
At this time swich off and extract the key. You have to wait until the MOST goes down(the instrument cluster goes off)
Insert the key and keep looking at comand screen.

If you select 251 version, you are able to find a new navigation mode named OFFROAD, very nice, with steering angle altimeter and compass, plus position.

Keep in mind that when you let most go off again, the information will return the original ones, and you losto the mod.

I am sure that is possible to lock the change and enable mp3 and dvd from this menù. look at this:

The image in the link shows a group of 3 function that are:
Dr.Dist(Driver Distraction) this function is able to avoid TV off at ten Kmh
BackDoor: Not sure of the function
RegCode: this is the item that can manage the reginal setting. You can fix the modification of your Comand version from Here.

I have found that in some version of comand holding for more than 10 seconds the following key combination while in engineering mode, you can access these functions:
* +# + Arrow on the left (in the right navigation pad)
1 +3 +Arrow on the left
1 +3 +9

on my 203 of 2005 none of these combination works.

Anyone has other informations to share?
A good stuff is the demo mode in navigation that is accessible in 203 / 2005 comand.
go to nav screen
press 5 and hold it while you press NAV again. Hold the keys until you enter in a large section of hidden function:
