Hello. I bought this receiver and the Detrum GAVIN-8C 8 transmitter. After pairing them, when I go to the settings, the transmitter displays the message "unable to connect" with GPS. I have a question: does the small triangle on the plug mean GND? Does it connect to the outside of the receiver? Thank you for any help you can provide.
(edit: I already read it; it was in a YouTube video by Dynam.)
