Sometimes, it's the little things that make a rig more cool day to day.
I usually drive with a radar detector, so I needed a way to charge phone without taking up the cigarette port up front. Found that Cali Raised LED has this great little USB charger port that goes in one of the switch blanks in the console (
Toyota USB Outlet). Wired it to the back of the cigarette outlet and it works great.
Additionally, when driving off-road I typically use OnX Offroad for mapping. I don't want to change out the head unit yet, but it would be nice to actually see what the map says at a glance. I grabbed one of the Scosche magic mount pro magnetic mounts and popped in under the vent as a temporary measure. To my surprise, its worked even on some gnarly trails. Not sure I really need anything else.
The last mini interior mod was my inclinometer. I found one that even matched the interior color scheme of the lights! I took out the little pop out drawer thing below the vents that I could never find a use for. I initially just used command strips, but those kept coming off in the heat. Got tired of messing with it one day, and finally drilled some holes and screwed it to the plastic. Love the look though.
