Here's another "has anyone tried" post. Has anyone given this a shot?

HU_CICHB ==> 3000 HMI ==>L7_SURROUND_CONFIG

There's no comment for this parameter. But I am wondering if it permits configuration of the HK system beyond just tone controls. In the L7 system in my early (2006) E90, there were three additional sound processing settings one could select to alter the sound stage. I've always thought it was odd that the L7 setting is simply or or off in the F30 and I'd sure like to try more signal processing settings, if any are available.
