If you're not sure about this whole iPhone turn-by-turn thing, and you've been too afraid to try it because the apps are so expensive, hey, look: Motionx Drive, our favorite budget iPhone nav app, is just a dollar right now.

Granted, this should be seen as a trial, because it only includes a month of full services, after which a navigation subscription costs $3 a month or $25 a year via in-app purchases, though the months don't have to be consecutive, so you can sort of just pay as you go, buying nav access only when you need it. If you're driving anywhere over the holidays, seriously, just give it a shot. Four quarters, folks!
