GPS Systems

Good afternoon Glenn,

I think the reason GPS navigation systems have the video display with the map on it, and not just the "turn left in 257 metres" audio messages, is that it is reassuring to see the map occasionally, and see that the GPS system does at least appear to know where it's going.

It is also helpful if you are sitting at a red light in a "foreign" city and you can quickly check where the GPS will tell you to go so that you can be sure to get into the correct lanes and also have an idea where you are going, which is much less stressful than hoping that the magic voice gives you the right directions.
