I can verify this, yes, seen quite a few strings like "Hash checking of files failed" and such within the CAB installer DLLs. Still digging on where the hashes are stored and what type of hash is being used .... so far, seems like SHA256 might be it as I found some strings related to it, but...

Wondering if anyone tried to also measure the negative lines with the audio outs ... my car is in transit still, so I can't do it myself.
Wiring looks to me...
