I could be wrong, but I believe you'll need to buy City Navigator for road routing?
Ah, but you could be right, too. That could be a good point! I'm afraid I cannot say either way. I see now I should have explained my perspective. I would, if in a car, use the maps but probably not the navigation. My wife, on the other hand, likes the box to tell her when to turn. I would just use the map for reference, so I honestly didn't sample its street navigation in that much detail. (I don't think the clerk wanted to go beyond the front door of the store where we went to get a good signal) ;-) And, also depending on your perspective, the add-ons sounded anything but cheap - it sounded far more cost effective to buy up rather than adding-on if you want that functionality.
