New 172 Satnav Questions

[Tom]

Does the Colour satnav on the 172 use the headunit for anything?

If i order mine with it can i change the hu for something else?

Tom, afaik there is no connection between the satnav and the radio, even the instructions etc come out of a speaker under the climate controls.
