The disco boys have been upgrading their D3's to fit the D4 SAT NAV unit.
You can also do this to the Early RRS too.

You fit a new display unit, which has all the navigation built in, (it contains a hard disc).
It will also display a reverse camera image (without GVIF) providing you have a GAP IID.

It's a better touch screen with new graphics and newer maps.

RRS specific:

Remove the top section of the plastic as shown on the D3 site.
Also chamfer the raised part to allow room for the fibre optic connector and GPS connector.
Get a heat gun on the heating duct at the top, and then quickly screw the display in place, so the duct sets in the correct place.

Thanks for that, being in NZ this would be very difficult obtaining bits, and getting NZ maps as well, plus reading through the post it only works on the Hi Line systems and not the lower base model which i have got, love to take it on if i was in the UK.

I have fitted this to a 2006 rrs but can get the reverse camera to work i enabled it with sdd but i do t know what else needs doing. I can see image on hidden page.

It’s not enough to enable the camera.

The gap iid does some magic stuff to get it working as per a year 2010 car.

Try saying it’s a 2010 car
And 360 not fitted

Would changing car year do anything to upset the car. Do you have sdd to see whats changed

Did you fit a rear camera

I don’t have an sdd

Yeah I fitted a camera. Used gap iid to enable. Selected camera MY10

It’s a cheap aftermarket camera
