The video shows the detail steps to install three option modules. If you need to install the GPS, Compass and Lora modules by yourself, you can refer to the video to do it.
This seems like a wonderful rig!! I'm surprised it's not getting the advertising (at least here in the US) that XIegu's G90 has. Both seem like awesome rigs, with VHF/UHF on this one!! I own a G-90 and I think I'm gonna buy one of these this year.
This unit is full of bugs don’t buy it, you get no support and the unit is shipped direct from the production without being tested for functionality’s. Hands off
