Sweet lordy.........
All of the comments jibbering about the evils of sat nav are bloody rediculous. Yes, if you follow it off a cliff or into a river you deserve to be publically humiliated for your lack of sense, but for the rest of the population who display even the most basic notion of possesing a degree of common sense, sat nav is undeniably a huge step forward from battling to read and navigate from paper maps, sometimes while trying to drive (you know who you are maptards!), other times stopping in dangerous or obstructive places on the road to get their bearings again having missed the turn that they needed. Sat nav would just re-route in a few seconds.
Anyone who is under the impression that (most) drivers with sat nav are fixated by watching the pretty moving pictures while on the go is a numpty, (a minority may do - but they are the type who drive off cliffs) The audible instructions from sat nav are no more distracting than having a passenger giving directions, and are a lot more accurate and faster to re-route than a passenger with dubious map reading skillz.
I fail to see how the addition of a TV tuner turns a sat nav into a lethal weapon, as some seem to be implying. In-dash tv's and DVD players have been around for years, so why is this device any different, or any more likely to make a driver think that they have the ability to drive without watching where they are going.
@the bigyin
You must be one hell of a driver if you know every single road so well that being given prior notification of the layout of the road ahead (beyond your line of sight, and not including obstacles like other traffic and animals) is of no use.
I applaud your super-human brain power!!!
For the mere mortals among us , when driving on unfamiliar roads I would have thought that anything which aids a driver to make a better judgement of the road ahead, well in advance, would be an advantage.
As for "Always be able to stop in the distance you can see" fair comment. But what do you do when confronted by very sharp blind corners or blind summits? Proceed with absolute caution would be the sensible thing to do, but wouldn't it be clever if there was some kind of device, a tool of the devil, that could indicate in advance the shape and layout of the road beyond your line of sight? Then at least you would have one less thing to worry about, and could focus more on road conditions and hazards on the carriageway.
