NAV 2010 and going on the road with dial-up connection

hello,

 

I am going to be taking a trip into a place that does not have broadband, so I am curious how log it would take me to download the live updates via the modem. Can I postpone them until a later date and then have them update automatcally? Or turn off live update?

 

thnx.
