Good afternoon for all ! I´am end the end of telephone retrofit, and now I face issues with coding of Phone unit.
I have strange thing on my VCDS with unit 77 telephone. I want re-code the unit because I fully retrofit phone (phone unit, button for phone on steering wheel) but I didn´t see inside VCDS ,,suggest,, or possibilities coding for this 77 unit.

I see only some default coding from previous vehicle, but I have no idea what mean or for which value I must change it, when I want saw data from phone (incoming call or phone list) on Maxidot and control the phone via wheel buttons (I also code the unit for wheel for version with phone 00119).
Parallelly with this I cannot change coding in Navigation system block from 00002 to 00004 - value is still 00002 - I don´t know if is it neccessary.

I double check the wiring but this should be good, VCDS recognize the unit, unit itself working well (I should call manually from phone, and I hear the voice from car repro) but I have no idea why is this happened or which coding for 77 I must use for all functionality this system

Car is Golf mk4 (2003 with CAN), DX navi+TMC box, and Telephone unit 1U0 035 729 C - unit is from Skoda but this should be good.

Could somebody help me with this coding ? Maybe the list of possible coding will be really helpfull :)
