Need help with binding to QX7 Taranis

[cableguyp]

Hi so I have the Taranis QX7 and I updated the firmware to OpenTX 2.3.7. I am trying to bind my drone that uses a Tx5258 transmitter but it won't connect. I am holding the bind button when I plug the battery in and give it like 20 seconds before giving up. I don't know what to do, I'm using the internal RF on the D8 mode.
My wiring is as follows:
T5258 Trasmitter-
DC7-24V to VCC
Ground to Ground
Video to VID
Ground to Ground
Smart Audio to TX3

Matek 40CH Video Transmitter-
Positive to VCC
Ground to Ground
Video to TX3

Camera-
5V to 5V
Ground to Ground
Cam to CAM

The camera video feed works but for some reason no matter what I do I cannot get it to bind to my Taranis QX7

Okay I'll go.
It sounds to me like you're mixing your understanding of radio & video parts a bit.
You mention T5258 Tx and camera for the video parts.
You make no mention of a receiver (Rx) to go with the QX7 for the radio parts.

Yep sounds like you're trying to bind two transmitters, it don't work that way. You have to bind your qx7 to a reciever.
