when you go to a higher trim level, you can see what the higher trim offers standard versus the previous lower trim, and the sensor is not listed on any of them. You would think they would list that! I think its a pretty big deal pesonally! I checked all key enhancements from one trim to another, and its not listed.
EDIT, its not listed as a key feature, which you would think they would! That is very much a key feature!
It is listed if you go into the models and compare everyone side by side and see every standard and optional feature available for every model. To be honest, I have never been to that page before lol. Always just looked at the key features! I just knew the limited came with amost everything so I got it lol
