Hi I am new to this forum, i hope that someone can help me.

I am setting-up (for study purpose) a MOST optical ring.
I have an NAV-HU from a Mercedes car on the side label there are some number:
HARMAN/BECKER
Model BE 6094
A 164 820 09 79
A 203 827 00 62

I can't find a complete pin-out of FACKRA connector.

My first necessity is to find MOST electrical wake-up signal.

Thank you

All you need to do is order the complete wiring harness from your local dealer. Will save you huge amounts of time, comes complete with wiring and connectors and also has a fuse and ground plane.

Without an optilyser you may find that studying MOST is very difficult without an alternate method such as a PCI card interface.

I understand your question but I dont understand how you are going to benefit from the wake-up pin. The W203 and W164 MOST navigation already has an audio-gateway so if it is a new unit it will not have any memory presets and will boot just fine with power supplied.

The factory harness is quite obvious in all aspects relating to the pin out. There are only 8 pins of consequence. These are the main power pins, wakeup, CAN and so on. The other 8 pins are speakers and then you have a block dedicated to the AUX port.

In one 24 hour period you could obtain about 6 months worth of reading material for a very low cost.
 
Hi Oanimo

Firstly, let me welcome you to the forum. :bannana:

As for your post, you have lost me I am afraid. Perhaps you could describe in a little more detail what you are trying to do?

What is a MOST optical ring?
 
Most

I have an Optolyzer with sw.
My HU now is returned to the owner; usually I can test just for some hours so is impossible to order and receive the harness.
Buying all HU models appears an impossible task because of lot of models and high prices.
I have a CD changer with MOST connection the a 3 way connector
1 +12V
2 GND
3 WAKEUP (from newtwork master - HU or AGW)

You tell about W203: is it the Head Unit Becker 6094 ?

Thank you for info
