New York Times:
Free smartphone navigation apps from Apple and Google offer turn-by-turn driving, walking and biking directions. And many new cars have the option of built-in navigation systems. So is there any longer a reason to buy a stand-alone GPS unit?While smartphone navigation apps have some advantages, including limiting the number of devices one needs to buy and carry around, they also have some negatives.
I’m still a huge fan of stand-alone GPS devices for the reasons stated here and many others. I’ve tried almost every iPhone navigation app and I still come back to my Garmin or TomTom GPS on my motorcycle. If you’re just going around town, the phone may do the trick but, if you are travelling and/or wanting to “customize” your trip, a dedicated GPS is the way to go.
