Ok. I've hit the "ohmagerd, I want to change my order" phase. It's not locked for another 10 days or so, and I'm wondering if I should get the parking sensors. However, I AM planning on getting an aftermarket stereo/nav, and so I'm debating if I wouldn't be better off going with parking sensors from a laser jammer (something I am planning on getting anyway). I imagine the "screen" from the sensors would be lost with an aftermarket infotainment screen, no?
