The EVO-REMOTE-1 is a 1-Button 1-Way plug-in RF remote and antenna upgrade system. Start or stop your engine with the push of a button from up to 1500 feet away. Depending on vehicle and data module coverage, functions also include lock and unlock. This system comes with (2) 1-button transmitters, RFA2A antenna adapter, the antenna and antenna cable. IMPORTANT: This is not a full remote car starter. This is an add-on remote control kit that works with Fortin “Stand-alone” remote starter – systems that consist of an EVO-ALL or EVO-ONE module only and do not include a separate remote start module. If you have an EVO-ALL or EVO-ONE that was NOT purchased from MPC, you will need a FlashLink Updater to make this product work. EVO-ALL or EVO-ONE stand-alone systems purchased from MPC have the correct settings and the updater is not needed.
