My car has the Speed Limit Info, but I did not choose LDW - hence this project of getting LDW working.
In reality, LDW is working on my car with just coding it (even without the steering motor) - the car detects the lanes and everything ; the issue is there is no driver feedback - that happens through the steering vibrating motor.
aah makes sense.. damn, i dont have either... nor active cruise control nor speed limit info..
