I like the Topo maps over the flat ones I have. The Honda/Acura Navi has a long way to go. I am wondering tho if you can use the Alpine maps in teh Honda system. They are both Navquest type maps, no?
Never really tried it. It may work. They are both by NavQuest. The displays, i.e. topo/flat are dependent on the nav system, as opposed to the data on the CD.
