Rear cross traffice monitor upgrade for prior 2016 models

Hi,

I bought back in November a 2015 MDX Adv. and Ent. This is my first MDX and I love it.

Does anyone know if there a way to upgrade the 2014/5 MDX with the rear cross traffic feature? My car is already equipped with parking sensor and a backup camera.

I am looking forward to see your answers.

Have a great day.
