Hi,
Some time ago, have coded item 1 on my car, which has HK audio system. This option replaces the HK L7 surround processor (only on or off) with a multi-option one -- and it really does make a difference
Adding option 2 doesn't seem to do anything to either improve surround sound or add B&W logo
Having said that, option 1 is well worth it and easily coded with Bimmercode or E-SysX
