Can’t say I’ve ever seen this
Obviously I haven’t seen everything available on a GMT-800. (I only just recently learned rear heated seats were available) I’m learning and I have questions…
Where is this installed? Is the year range accurate? (I’m aware 99-2002/3 wiring is different than 04-06/7) Can it interphase with any GMT-800 or does the computer need to be factory setup for it?
