Use Your iPhone as a GPS
There are many ways you can use your old iPhone as a GPS system.
For starters, you can get a car mount and turn your iPhone into an offline GPS, so you never get lost while driving. Not only will you be able to control where you’re going, but you could also connect it to your car and use CarPlay to make your trips more interesting.
On the other hand, if you carry a lot of stuff with you, you can take your old iPhone and turn it into a GPS tracker. Thanks to the Find My network, you can keep track of all your Apple devices and other stuff with the help of an AirTag or a Tile.
