PTC supplemental Heater

[GLW]

I have this item listed on the dealer invoice as a $250.00 option and I can not find out what it is or if I really have it. I do not have the fancy heating system just a single controller nothing for the passanger side. Any suggestions or thoughts.

I also have advanced security group and have no idea what that is either. is ther a place to go and find out what these items are??

thanks, Guy

I bought a 08 XLT Crew cab Automatic 4X4. Yesterday!

(requires diesel engine, air conditioning, extra heavy-duty alternator or dual alternators)

I have the supplemental heater on mine and it sure is nice. If I warm up the truck for 3-5 minutes on cold mornings (25 degrees is about as bad as it gets here), it's quite comfortable inside. Plus, it keeps Wife 2.0 happy (that and the seat heaters).
