Set-up is a snap, just plug it into the OBD port and you are set. No drilling, no wires to run (except as noted below) and downloading the App was a breeze. The user interface, has a quick learning curve and the next thing you know, you are on your way with full tracking. I like the fact that my system is 4G rather than 2G or 3G like some of the cheaper GPS systems I looked at.The only downside was not caused by the unit, but rather by my Jeep. My OBD socket was located where my foot would sometimes kick the unit when I got out of the the Jeep (I wear size 12 boots). This was easily solved with a $7.99 OBD extension cord that let me relocate the GPS unit (and at the same time, hide the unit a little deeper under the dash).The unit seems well built and nearly bullet proof.So far, a happy customer. I will update the review if anything changes.
