Wondering if it heats just the butt or if it does that lower back also. The onscreen pic just shows the bottom. Thanks in advance
It is a pretty comprehensive heater, seat and back. I've been trying to "high mile" my S, so I leave climate control off and seat heat on, unless the windows fog. I imagine as we get into the January cold snap that won't be tenable, but for now it has been working great for me.
A couple of cars ago, I had one where you could control the seat bottom and seat back separately. Loved that. It was great for a tired, sore back when you didn't want your butt overheated! Depending on how the seats are wired, that could be a software update wish list item. Wish the seats were cooled/ventilated too; I really like that in summer.
