So I got this as a Christmas gift from my bro... seat warmers professionally installed under the seats with switches. Love them!! So comfy. Very evenly distributed heat. LED glows amber when set to low, and red when set to high.
Oh and also I bought the Pioneer AVIC-S1 portable navigation unit last fall after going camping. My bro had a demo unit and I loved it so much that I ended up going out and buying one for myself.
And this is the product:

# Includes both seat bottom and backrest
# Requires no cutting of upholstery
# Hi / Lo settings
# Thermostatically controlled
# Relieves back and neck pain
# Reduces driving stress
