Axxess AXSSO-GM is an interface designed to disengage the STOP/START feature of compatible vehicles, and keep that feature disengaged even after the key has been cycled. The AXSSO-GM is compatible with either aftermarket or factory radios and requires a simple 2-wire installation (ground and power to the battery). Once installed, the AXSSO-GM will allow the user to override the STOP/START engine feature, which can be useful in situations where the user wants to keep the engine running, such as when idling in traffic or when using accessories that require power.
