Its a field GPS.
Mark each turn as a waypoint and watch it...Ergo you can see with that necessity and looking at a small screen is a very poor way to drive with it.
No way does it beep anyway.
I dont have a smart phone but believe some of them have apps for navigation.. Perhaps with sound.
And a car only GPS is so cheap now..they are becoming obsolete.
When you ask a field GPS how to get somewhere it will give you a straight line path no matter what is between you and the destination. It could be road, a canyon could be there, or a waterbody. They require a bit of discretion and awareness.
Car GPS units only have a memory of roads. While they tend to also follow straight lines you will always be on some sort of road.
