I installed a Grom adapter today so I could have a direct hookup on my phone. I am happy with it except for my auxiliary mount. I basically took the male end of the Grom cable and have it plugged into a female/female coupler. I drilled a small hole for the female/female to slide into, where most of it is behind the dash and just enough sticks out for me to actually plug a male/male into and then into my phone. I hope that made some sort of sense. It is between the cigarette lighter and the power source, above the cup holders. It doesn't look terrible, but I would like to have a more factory look to it.
I was hoping for something sort of like these pictures; that looked like the factory switches like for the fog lights, rear diff lock, etc. The only thing is that it needs to be female/female and I've had no luck. I was just hoping somebody could point me in the right direction.
