What did everyone pay for installation?

[brad 10+ year member]

I am looking at getting a viper 791xv instaled in my car and was wondering what everyone has payed for alarm installation.

If anyone has a viper 791xv what was the total cost including installation.

I know that my install will require the GM passlock interface.

If anyone has a GM that has the driver 1 / driver 2 memory controlled by the factory remote, does this feature still work?

791 and basic installation is about 500 but that doesn't include the bypass mod, prob an aditional 150. the trailblazer is databuss so you would need a 457g from dei.
