just a small update... if anyone knows how to edit a cab file... changing linespeed to 350 made a HUGE improvement to my car's bluetooth. it's set to 320 in the cab i linked.
Once the CAB is applied, can't you simply reg edit the lines King referenced earlier?
This cab does not actually install or modify any files; it simply makes some registry changes. You can go into the registry editor of your choice to see if the following keys look like this:
[HKEY_LOCAL_MACHINE\Software\Widcomm\Plugin\AV]
"LineSpeed"=dword:00000140
"SubBands"=dword:00000008
"Blocks"=dword:00000010
Seems simpler to me than trying to unpack, edit and repack a CAB.
