By separating the compact display and controls from the bulk of the unit allows for more mounting options. The 1meter cable that connects the two allows you to hide away the heart of the unit under the dash, while the controls and display can be easily mounted where convenient.
The simplified functions ensure efficient operation.
Besides being easier to mount, the new unit also includes mph or km/h Speedo and a Clock.
All for the same low price as the original auto timer.
