XTRONS Mercedes-Benz Car DVD Player CANbus Solutions
In order to provide you with the best in-car entertainment solutions, XTRONS has worked hard on the communication between your car and the XTRONS vehicle specific head units for Mercedes-Benz.

XTRONS has now developed the dual channel CANbus solutions for the below model numbers.
The dual channel function is applicable for all of the following XTRONS Mercedes-Benz Infotainment Systems: PF75M245A, PF75M245AP, PF75M164A, PF75M164AP, PF75M209A, PF75M209AP, PF75M211A, PF75M211AP, PF75M220A, PF75M220AP, PF75M203A, PF75M203AP, PG75M211A, PG75M245A, PG75M203A, PF72M203GT, PF7M245GT, PF72M245GT, PF72M211GT, PF72M164GT, PF7M211S, PF7M203S, PF7M245S.

The following information can now be retained:
Steering Wheel Control: Take control of your music safely on the move.
Headlight Control: When the vehicles headlights are on, the buttons on the XTRONS unit will illuminate while the head unit are off. XTRONS units can also switch to night mode when the headlights are on.
ACC: The stereo will automatically turn on when you start the ignition.
LCD Screen: XTRONS units working mode can be displayed on the vehicles' information display.
Reversing Control: The stereo allows automatic switching to reversing mode without the need for additional wiring.
Due to the different design of the various Mercedes-Benz models, we had to make some adjustments to the CANbus box dial switch to enable the correct CANbus function. In the below table, you will see the information on how to adjust the provided CANbus box dial switch and for which vehicles the adjustment is required.

I have a PDAB7M203, installed in a Mercedes C class (W203).
Even though the steering wheel buttons work, there is no radio/nav/tel info shown on the dashboard LCD screen.

How do I set the canbus so that this works as well?

The capacitor is for the ringer. It is not connected to any part of the tone dial circuit.
YOU are talking about A and K on the network, right?

I have just installed a PDAB7M203 into my Mercedes C180, W203, 2004. everything works fine except that I cannot programme the steering wheel buttons. In the steering key screen I can use the clear all and confirm buttons (they go blue when pressed) but pressing a steering wheel button has no effect except that sometimes the numbers on the screen above the button icons flicker but do not change.

I have installed the latest upgrade to the software and nothing has changed.

Has anybody else had this problem and is there a fix for it?
