My Tacoma has a backup image in the rearview mirror. I only drove it for ten years before I discovered it. I remarked on it to my wife, who's known about it from the beginning. It's about the size of a postage stamp and might tell me if I were about to back into a T. Rex. A mailbox? Fuhgedaboutit. I'm still not using it...I’m still driving an ‘06 RL we bought new. 282,000 miles and still drives and rides great. I just put a new set of Michelin’s on it. It’s never been in the shop other than for service.
Last summer I pulled the radio and installed a touchscreen and a backup camera. The radio was easy. The backup camera was a challenge.
