I'm contempating purchasing my dad a sat nav for his birthday, however, I know nothing about them and it seems there's a massive variation in price - from say 50 to 200 etc.
As I understand it different sat nav systems run different sofware with some being vastly superior. Also, when you purchase how do you get updates to roads and stuff? - Is this something you have to pay extra for or something that comes with it?
I'm not looking to spend a fortune but I don't want to waste £50 on a device with ancient maps and a crippled OS which is a nightmare to use.
Also, since my dad's no spring chicken or tech whiz I'm looking for something easy to use.
So, can anyone answer my questions firstly about how these devices and stuff work, and then perhaps suggest some good ones?
Many thanks in advance :D
