first of all please excuse me for writing in english - i do not speak russian.
I have a A4 B8 model year 2010 with an 3G Unit built in from factory.
Now i retrofitted an 3GP unit to my car.
This 3GP Unit was formerly from an A8 with part number 4H ...
After flashing the Unit to K767 SW and some changes to the EEPROM
everything works well -
almost everything.
The sound is bad -
it is hard to describe in what way it is bad
but there is definitely something wrong.
Sounds like it uses some sort of wrong soundprofile
wrong DSP Setting whatsorever.
Did anybody experience the same ?!
Any idea what could be the reason ?
I already checked almost any possible setting in the green menu
without any success.
I think it is something inside the EEPROM.
If i switch back to the old unit - the sound is perfect.
So i think the problem is inside the 5F Unit and not
the problem of the B&O Amplifier.
Well, 56 is the radio unit RU
i did not change anything on that unit
if i swap main units MU (3gp <-> 3g)
sound changes from good to bad and vice versa
Du you really think there has to be done something on device 56 ?
B&O has its own amplifyer - it is device 47.
56 has integrated amps for standard soundsystem und audi soundsystem
b&o has a seperate amp.
@ladadens[CENTER] : You mean the EEPROM Parameters in the MMI 5F right ?!
That is what i suspect too.
Anybody any information on how the correct coding is ?[/CENTER]
The acoustic preferences are set in the MMI 3GP unit, the B&O is just a digital amplifier. I have done a retrofit with a 3GP on a 2010 A4 avant with B&O.
And the sound was better than with the previous 3G. I confirm that Vag can pro can change the car dimensions for a 5F unit.
The problem is in the B&O amp 100% sure, use vagcanpro zdc file for b&o parametrizing after you did fw upgrade to 767 you officially need to do an svm coding to correct the parametrizing, so go to dealer and do svm or buy vagcanpro
как изменить сочетания кнопок для входа в режим обновления, аппарат 3GP китай, на родной клаве работать не хочет, на клаве от RNS работает, но нет кнопки возврата для входа в меню обновления.
