Hi
I have been going through the site extensively and frankly I am having some trouble working out what to do - a bit like a map & compass, until I have been shown/told what to do I feel all at sea...

So I have a NUVI 3760T. I have previously managed to get the South Africa map onto the machine but that was several years ago and subsequent gallons of wine and spirits have erased all memory of that feat. What I am trying to do is update the GB map and also to add the Canada/North America map for a trip I have later in the year.

I downloaded the Garmin City Navigator NTU Image but it's too big for the memory I have on my GPS.

Any help/steer would be very much appreciated and I apologise for being rubbish in advance.

Dan
