Recently purchased a 791xv from an authorized viper dealer, had it installed at the same place, i brought them the two up and down window mods (530T) as well as the sunroof mods (529t) first they tell me that the sunroof mod will not work due to the different positions of the sunroof (vent, open and close) said it might open the roof when I actually want the roof to close?? Second they put all 4 windows on one channel, therefore when I want the windows to roll down, all 4 go down instead of 2 front or 2 rear. another problem, if the windows are down and I remote start the vehicle, the windows roll themselves up but stop when the vehicle cranks to start!!! Another thing when I disarm the vehicle the perimeter lights that are in the factory alarm do not come on. Any suggestions.
