Not at all intrusive. Was a very straight forward install as I had them take the power from the glove box and up the A pillar. I printed instructions for them and they were done in no time. As I don’t have a pano roof, running the rear cam was easy too, but not a big deal for a pano roof. The newer versions of it have a better straight power/data connector (instead of the prior L) for the rear cam that easily fits through the boot cover that delivers power to the lift-gate from the ceiling.
