I have the bird view system, I like it up until the point someone says "here's the postcode" at which point bird view fails. It only takes street names and towns, which can be troublesome.
Yeah I just don't get that at all, I have the same thing with my OEM nav in the Leon
The Navman in the Zed lets you enter whatever you want in whatever detail you want i.e. post code on its own or postcode, then road then house number etc.
It's the extras too it cost me £20 for a traffic add on that updates and routes you around black spots with no subscription and I paid £25 for a years worth of speed cam updates. You get free map tweaks here and there as well, but you do have to pay when there is a major update which is fair enough I guess
Only thing with mine is I think I have fried the battery not really an issue as when the ignition is on the nav runs from that anyway
