ICARSOFT HD V4.0 CUSTOMER REVIEWS

  Barry Creighton, Poole, UK

As a fleet manager, we need to keep our trucks on the road. I previously had a much earlier generation of the HD tool by iCarsoft but it was very limiting. This new V4.0 is a whole new ball game, much more responsive, huge vehicle database and system coverage (although it depends on whay bus or ttuck it is hooked upto) and come with the connecots for different vehilce types. happy with this and would recommned if you want me to I can share with others in the trade. 

More reviews coming soon...
