Truck Sat Nav

I have noticed 2 or 3 sat nav systems that have now been released on the market. Has anybody yet taken the plunge and bought one of these units? Can anybody tell me yet what there experiences are of them? On the face of it they seem like a great idea and I have been complaining that no-one has introduced one earlier. If anybody has information that could help please let me know.

hi clarkie.
Read the other tread on truck satnavs there’s plenty of advice there.
