3 - Dont'know :-) The thing within this thread is about the aspect of two types of combox modules, the media version and the telematics. Physicaly the main difference is TCU capabilities and some extra wires. In this thread we mentioned telematics because I had connected power to pin 2, pin 2 is the powersource for telematics, pin 1 for media boxes. No problem to connect both, but on a media box this results results in a "fake/incorrect" reporting of the ecall (telematics) ecu, while my box has not the connectors/function...

4 No relation, no impact.. not the right question ;-) see point 3

Thanks.

I am discussing it to find a logic, difference and rationale of going for one over the other.

I have worked on E92, which had combox telematics. He had only pin 2 as the source of power. And I read on other thread that few people had issues when they connected the power source to pin 1, but as soon as they connected to pin 2, all went smooth.

I have a hunch feeling that;

1- 633 is connected to combox telematics and give you all the options on the CIC.

2- 644 works with the combox, but without using telematics and has less options.


I may be wrong, but I will strive to find out the answer of this.

Thanks.
