I am interested in possibly buying a Hytera HP682 radio, but I don't know much about it and I've never actually seen anyone use it. Not even in a youtube video. I understand that some gmrs radios can send gps info to an app on a phone to see the location on a map in the phone. Does the Hytera HP682 radio display the gps location on a map in the radio itself? Or does the Hytera HP682 radio also connect to an app on a phone that displays the location on a map in the phone? I'd like to see or at least know more about a few things like the user interface, menu, apps, and everything else the radio actually shows on its own display. Having to use a phone with some relatively cheaper gmrs radios for texting and sending location info is not as convenient as using the radio alone. That would be great if anyone knows. Thanks.
