sorry for being dumb, so without the Alpine KCA 420i can not connect a Ipod to the Intravee?
That's almost right, but you don't connect the iPod to the Intravee you connect the iPod to the KCA420 - the Intravee just acts as a translator and allows the KCA420 to connect to the car's internal network.
The Intaravee is a gateway device - it converts the car's iBus protocols to Alpine AiNet and vice-versa. The Alpine KCA-420i iPod adapter is an AiNet device so you need the Intravee to allow it to 'talk' to the car
