Yes but that doesn't get you sound .

Yes but that doesn't get you sound through the L7 amp
That only prevents errors like the SOS and PDC errors .
and allows the car to be updated its not intended for sound
for your music system.
If you look at that block diagram you see the fiberoptic link between the OEM head unit and the L7 amp . You are breaking that link when you move Head unit . I guess you could route the output of your new system to the aux
on the OEM radio and still run the the L7 amp with the same setup but I haven't seen anybody do that. The aux is noted to be a low fidelity input.
See if you can block diagram your system and show how sound gets to the L7 amp the way you imagine it.
This is why dynavin for example says not for use with an L7 system.
