Just beware that the Garmin online update routine requires the installation of 
several highly-invasive software additions including Microsoft DotNet 4.0 
before it can do the updates.  Play safe and back up your system in case all 
this software "sludge" breaks something else on your system.

Further, the download is not just an incremental update.   Rather it is a 
download of the ENTIRE latest version road data base from scratch.  If you opt 
for all of Mexico (new as of the last year or so) as well as all of the US and 
Canada, you are looking at 1.5-2.0 GB of data that can take the better part of 
a day to download.   I.e. it's almost like Bit-Torrenting an entire movie.    
The latest downloaded update also provided a nice color 3D-looking 
shaded-relief effect when zoom the map out to an area over 50-100 miles 
across.     Looks neat in the western US, although not much to see in the 

(I've updated an Nuvi 855 with lifetime maps twice now with no problems, except 
waiting for huge downloads.)
