I have a 2005 GX 470 that is a base model (no navigation system). I'm looking to install something aftermarket and purchased a Pioneer Avic-3 but apparently they do not make a dash kit for the Lexus with this system. Does anyone know of a Nav system that can be installed aftermarket in the dash. I don't want a mobile NAV unit. Ideally would like a system that has navigation, bluetooth, IPoD and back-up camera (all of these features are offerred with the Pioneer but like I said no dash kit available to install in my car)
