Answer .... very

Also, on the Gold Cruise I fitted, I chose the stalk with 3 presets as well as the usual + and - buttons.
Very handy as my 120 mile trip to the office involved frequent speed limit changes between 50, 60 and 70, as well as lots of Cameras en-route. So I set the buttons to 50, 60 and 70 (real speed via an EODB reader*) and could just press the right preset for upcoming road. Lovely
* This may be of interest... The speedos on vehicles are generally wrong, but weirdly the vehicle DOES know the real speed it is doing I have found when reading the speed from the EOBD port. Exactly why THAT info is not used for the speedo display is most strange.
