Check out here http://www.nav-plus.com/instructions/programming.html - value of 8 implies that your GALA signal comes from the vehicle speed sensor not from the ABS sensors.
My bad! I missed that this was on a C5 A6.AudiA4B6US said:Your A6 C5 uses a dedicated wire for the speed signal. Once you configured your unit for the A6 (STG 56, function 07, second digit) you are all set.
