Ahh so take it its really not that good then the old retro sat nav?
I've actually never used it: my Stilo Abarth had Connect Nav+ but no maps exist for New Zealand
Reading about Connect Nav+, I learned that it uses the wheel speed sensors to modify the GPS-acquired fix - so theoretically at least it is more accurate than a standalone navigation device. But in practice, technology has moved on so much since 2002 that I really don't think it is worth trying to bother with Connect Nav+.
one other quick one can I fit xenon lights to it? as in OEM Xenon Lights?
not the bulbs but complete light units also is this a big job?
I don't about the 147, but assuming you can find the light units like I did for my 156, it is do-able, but rather expensive. If you like the idea of adding suspension level sensors (one front, one rear) and making up your own wiring, that is the way to fit OEM lights.
Otherwise, there are lots of kits to fit HID capsules into the standard halogen units. By the letter of the law, that is illegal - it is not permissible to fit an HID light source into a unit designed for a halogen bulb - but in practice, I'm sure there will be people out there who have done just that and pass MOTs. The main risk is that light can end up scattered everywhere because the capsule has a different-shaped light source to the original bulb. As well as dazzling everyone else, you get big holes in your light beams. This is less likely to be a problem if your 147 has projector lamp design (which I think it does, at least on dipped beam).
Be aware that OEM HID lights are 4300K (colour temperature) and lots of aftermarket kits are much higher than this (e.g. 8000K) which you actually don't want. Sure it looks blue and 'bright', but you get more useful illumination if the light has some non-blue colours (not all roadsigns are blue).
It's still very tempting given the huge price difference between OEM light units (hundreds of pounds each) and a pair of HID conversion bulbs (probably around a hundred pounds).
You probably know all this, which is why you asked the question of how to fit original HID light units
