one of the options available for this perticular alpine alarm (8028) is tha fact that u can add other functions for the extra buttons such as turning on your alpine headunit, unlocking doors, or putting down windows...now to go to the retailer and have this done costs 50 dollars plus..I am assuming it is just inputting certain codes or something along those lines for the functions..am I right in this assumption? and does anyone know any of these "codes" I would love to be able to turn on my deck or have the remote unlock my doors so I wouldn't have to use 2 remotes anymore
