I have one. It is "AutoStart". I had it installed by an aftermarket
service shop. It is nice to have a warmed, or cooled car ready for the
go. Always have to remember to ensure wipers are turned off and Heat /
AC system is set appropriately for the start up - otherwise waste of
time and gas to run vehicle without desired heating /
cooling. Too bad
you cannot have the rear defroster come on automatically.
