If the difference wasn't noticeable, VWAG wouldn't bother making a separate file for each body shape
Yes. Car systems are definitely not like home / theatre systems where the speaker placement is alien and it's a closed space. At home I just let my Sony home theatre system with its plug in microphone bong all the speakers and do the adjustments itself 😉. Going to be something like that in these files getting the staging right and the balance for the cars body and speakers. I dont bother to twigg after the auto adjustment, leave that upto Mr Sony.

When I bought the Ateca there was a piece about how they setup the sound in a German laboratory. For safety and NCAP they smash the car at walls and dummies, for sound they do audio measurements to fine tune the system.
 
Hi.

My Leon 5F have Beats Audio (PR-9VG) with 5F0035456 amplifier (No MOST) , actually works with 5F0035877. no problems.

The Orignal MIB2 was swapped because the old customer install the Virtual Cockpit.

Im trying to make it works with 3G003521B (MiB2 Harman) but : NO Sound

All seems to be ok : Coding, Dataset and Firmware.

Perhaps i had an error somewhere , but NO SOUND for the moment : iI's like the BAP protocol don't work between the amp and MiB2 Harman.
