Enabling Pilot Assist and Adaptive Cruise Control

[IMAY2023]

Curve speed can be enabled but the software must support it.  I enabled it on My officially upgraded ACC / PA (replaced the unit and installed it via VIDA) but never saw it working. Maybe the roads in CA / USA are not all included, I don't know.  
Be very careful with installing the software. The PA software is in the BSM, CEM and some other modules. If you install a wrong software your car won't even start. 
Go to a dealer and just get a quote for upgrading officially.
