Digital Units (VDUs)

There are currently three different types of digital tachograph vehicle manufacturers – Siemens VDO, Stoneridge and Actia – in operation, and whilst the overall function of these units is similar, the visual display and navigation through the menu options is somewhat different.  Employed and agency drivers, those who operate multi vehicles that have different tachograph units, have been reporting problems getting to grips with the three units.  There are a number of reasons for this, mainly training; either training has been restricted to one unit type, or if drivers have been trained to use all three, this information has been forgotten by the time they come to operate a unit that they haven’t used before.

Here are some tips on the differences between the units, and some guidance on how to use them all.
