4 Windows Roll-up Module or 2 Windows Up/Down Automatic Car Alarm Scytek

Works great. Has vent function when used on a 2 window install. When armed it rolls up. When unarmed you can have an aux channel. Roll the windows all the way down.

The modules are garbage and the support as well, do yourself a favor DO NOT BUY ANYTHING FROM THESE PEOPLE. Technical support not only do they not speak english they are extremely rude and not willing to deal with any issues you may have. Avoid it all together.
