Bringing this post back from the dead...
I've been Google searching how to get the HK eq coded into 2 series stereos and found this thread:
https://www.babybmw.net/forum/viewtopic.php?t=81782
From what I read, this is what needs to be coded:
AUDIO_SYSTEM: hifi_system_harmankardon = 06
AMPLIFIER_VARIANT: most = 02
EXTERNER_MOST: aktiv = 01
VO is set to 677
I'm not near my car to verify this and I don't have the capability to code the VO (Bimmercode can't do this).
I'm wondering if anyone has tried this?
