I'm nearly finished with my tailcone kit. I'm planning on buying the Garmin G3X and it has the option of an action camera that can be installed in the rear tie down hook. I'm wondering if anyone has installed the coax cable and if I should run the cable before I close up the tailcone. I called Vans support and the gentleman wasn't sure and asked if I could email support instead. His thought was that I may need to contact Garmin. I don't want to buy the avionics until it's time to install.
