There used to be many competing programs
S&T though no longer in production you might get lucky on E-bay et-al
Though it's not been updated in what, 5 years, roads do not change that much.
Street Atlas (Rand McNalley)
Co-Pilot
I can't help you with others, Used to use Street Atlas at work (Half the computers had it, the other half S&T) and actually liked it a bit better than S&T but went with S&T for life on the road
Co-Pilot is or at least the early versions were, designed for Commercial Drivers (SEMIs) So they have special "Big Rig" features you may like.
