YES to g.p.s. but you'll want a TRUCK FRIENDLY VERSION like CO-PILOT and STAY AWAY from the 4 wheeler versions as you'll suffer much negativity quickly as MANY TRUCKING ACCIDENTS are the direct results of using 4 wheeler g.p.s. units.
"WHY did you run into this Bridge"?
"My g.p.s. said I could go this way"!
The MAIN PROBLEM nowadays is the seeming incompetence of many Newbies of not being able to READ A MAP or look up the RESTRICTED ROADS section of the applicable State.
ANY 13'6" trailer WILL NOT FIT under a 12' 8" Overpass/Bridge, yet EVERYDAY, SOMEWHERE, someone attempts such!!!
This is the Unit I use and it has worked WELL for me.
You're welcome to use whatever version, make, model, brand you choose but stay away from anything to do with mapquest.
