Hi - I am a complete newcomer to the world of Satnav - I am considering buying a new Go 6100 because there are some good deals. I am going to New Zealand soon and want to take it. Can anyone tell me if the NZ map comes pre loaded? If not is it easy to download maps and will I have enough memory. I have seen something about getting a scandisc but didnt understand that ? Also if I buy the satnav will it come with everything i need to plug and go or will i need to buy extra bits and cables. Sorry to be so basic.
