this is the mount we use and i have not found one better

as to mapping (gps) software the only trucking one is copilot (we have it on the company system and hate it) the one we use most is delorme 2009+ we also use M S Streets & trips, we like delorme better. we like the display setup better and it (for us) faster at setting up the route we are going to use.
some driver like streets & trips better and some will tell you that copilot is the way to go. it's a personnel choice and it comes down to what YOU like..
most of us (that use a laptop base gps routing software) use one of these
copilot 11 w/gps will run you $299
delorme 2009 w/gps $69
delorme 2009+ w/gps $99
M S Street & Trips 2008 w/gps $75
you my find them on ebay for less
