Open the Ziina app and tap My Violet on the home screen. Select CAFU and tap and hold to reveal your unique promo code.
Download the CAFU app and create or log into your account. At checkout, tap Have a promo code? and paste your code to activate your free CAFU Go subscription.
A few things to keep in mind: you'll need to add a vehicle to your CAFU account before redeeming, and if you already have an active CAFU Go subscription, you'll need to cancel it first.
