Use your old smartphone as a GPS

Looking to get a new GPS unit? Did you know that old smartphone in the drawer can offer you GPS services. Even without a cell phone plan you can still take advantage of the phone's GPS capabilities. There are many apps available, and you won't even need to have internet to use them. Just make sure the GPS is turned on and you're ready to go. The first app worth mentioning is the standard Google Maps. With Google Maps you can now use the maps offline. Just download the portion of the map you need before your trip and you can use it without internet access. There are some draw backs though, as on a long trip you might have to stop at a Wi-Fi hotspot and download another portion of the map. Another app available for free is call Navfree. Here's the description from the app itself

Unlike many other "free" satnavs we offer you fully featured, non-timelimited turn-by-turn navigation. No hidden payments: after map download you can use it forever for free and update it from time to time, also for free.

There are also other GPS related apps that may come in handy. One is called DigiHUD and will tell you your current speed while driving. Another is called Get Altitude and like the name says, allows you to get the Altitude of a particular location. There are also apps available for running.
