I started using google maps offline a few days ago and it works really well. open maps, make sure you're signed into a google account and tap "offline areas" while on wifi. it'll let you save a map of a fairly large area for use without an internet connection, and with location services turned on it'll give you turn-by-turn navigation. it took about 500mb to save the area from algonquin to the north, upstate pennsylvania to the south, london to the west and kingston to the east. put the tank bag on, the 10" tablet in the window pocket and voilà! free offline gps navigation on a ten inch screen. even saved a chunk of the US for when I hit the road later this month. the only thing it's missing are some crucial points of interest (gas stations) that it can't seem to find without an internet connection. still, pretty sweet.
