Jim- don't that. the difference is so minuscule that there is definitely no need for a 3 toggle L,M,H option. The part that my body contacts literally warms to room temperature and that's it. In Michigan it can be negative numbers outside. Additionally, why did they advertise a remote heated seat and make a toggle button, if they changed the system so that in fact the seats CANNOT warm up unless someone is sitting in them? false advertising. Old system WAY WAY better. At least then people had the choice of how warm they wanted the seats. Now, they advertise that there is a choice when in fact there is not.
