What is the difference between the CM19 and the CM25M?
The CM25 has a built in memory function enabling the vehicle to go to a pre-set speed at the touch of a button. For example: set the three buttons to 30 mph, 40 mph and 70 mph. As long as the vehicle is in the appropriate gear (with a manual gearbox) the vehicle will increase or decrease speed to reach the pre-set speed. Automatic vehicles need only to be in ‘drive’ mode. The CM19 one would need the CM8 add-on module (an extra £22.50) in order to utilise the pre-set speeds. The systems also work by twisting the stalk in order to set the current speed. The cruise will only increase or decrease speed by around 15% so as not to cause ‘surging’.
