Hi there,
Thanks for the replies. To give you an update:
Had the 3100DVD fitted and it’s superb, I’m very happy with it. One thing I like is that while I don’t have the special Pioneer lead that allows control of the HU from the iPhone, I can actually still control the HU through my phone using voice control on my 3GS using a normal USB cable. This is handy and a lot safer I feel than scrolling on the move!
The OEM sat nav does still work but the sound does not.
The steering wheel controls do not work. I had it fitted by Road Radio in Greenwich, they told me there was no loom for this, I’m not too worried about this anyway. I’m sure there are more specialist fitters out there for the Z, but these guys did a good job.
The Halfords camera is superb! Both the Pioneer and the unbranded one they had in their shop would have required a more intrusive fitting (drilling in the bumper, etc). This one is tiny and is fitted just by the boot release. It only costs £80 and Road Radio fitted it for £40 at the same time as doing the HU. Image quality and wide angle are really good.
Thanks again,
Rob
