I have had standard fit sat nav since 2004, the lastest car comes with a 7" screen, interfaces with the stereo and bluetooth phone, and also turns onto the reversing camera picture.
Updates are available for £40, i never bother as the position cursor still shows the car position, and the map the plotted route, so its not difficult to work out the correct direction.
Personally i wouldnt buy a car with out it.
I tried a smart phone for a walking sat nav, the display was hard to see in sunlight, it sometimes failed to lock on, and constantly needed to log on to find its position, i found it totally useless.
Replaced that last year with a dedicated sat nav, a Garmin 1370T, thats brilliant compared to the phone, and still shows your position and direction off road, the smart phone just left the position indicator at the last road you was on.
Comparing the Garmin against the Nissan satnav, side by side, the nissan blows it away.
The Garmin does give safty cameras, but even the last update is inaccurate.
The only advantage is you get full postcodes, nissan does'nt, however the 2012 models do.
dont knock people for buying sat nav, the second owner always gets a bargin.
