Hey all, new to the forums. I may be driving off with a 2012 Prius Four in Sea Glass Pearl w/dark gray interior this weekend if all goes well. Question for peeps in the know: can the Toyota VIP security system be installed by weekend do-it-yourselfers like myself? I know the unit is available for sale as a standalone accessory online. I've read the installation instruction and notice a couple of steps near the end that calls for a technician to jack into the diagnostic port and turn on some options via software. Is this required and are Toyota techs the only folks who can enable the software options? (If that's the case, I may just add it at the dealership.) Thanks for all answers!
