I'm curious as to how you will add circuit breakers and you own ports? Any chance you could give a little more detail or direct me to more information? Also, I've had other vehicles that kept one power port live and it was a nice feature to have when needed. Thanks.We recently bought a 2016 explorer sport 3.5 ecobeast, super high tech touch screen!, but we went camping, and you can't use power ports when it's off? 🤔 i plan on adding circuit breakers and our own ports. And a simple 3.5 input jack would be nice!,....and if you put a SD card in it, it affects the navigation? We love this truck, I'm sure I'll figure it out eventually.D.K.
