The SharkFinMod involves using a custom Fakra Z splitter to connect to the factory shark fin GPS antenna on the roof of your GM vehicle. This mod aims to enhance GPS signal reception by utilizing the existing shark fin antenna rather than relying on a separate GPS puck. The setup results in a cleaner installation and can simplify the wiring process by using a single cable solution. The splitter consists of one male Farka Z connector and 2 female connectors.
