To use the window roll down/up feature you would need an additional window roll down module. The MFC talks to the window roll down module and tells it when to roll up/down the window.
An alarm system with a negative trigger would be necessary if the MFC is used to control an Alarm System with or without auto-start.Or just upgrade to the MFC V3 package that comes with a complete alarm system with autostart.
Another one is the ignition bypass unit for cars with chipped/encrypted keys. It just sends a tricked signal to the car’s computer so that it can start the engine. This applies to any general remote starter that is installed in any car with a chipped key (mostly with newer cars). Otherwise the MFC is all you need.
