ez way to bypass is to just ground it straight to the head unit
not a universal thing. some head units require a relay in the bypass while others can be a straight ground.
i think some gps nav units even tied in the gps so it can tell you did a bypass because it knows when the car is moving.
easier just to google your specific model instead of going with trial and error since different companies and deck generations have dealt with this issue differently.
