GPSunderground again the 2012 ones called V4, you need to burn them to a CD using a specific CD writer program at 1x speed
 
I cant remember exactly what I did now I thin you download all 4 parts and unzip them to the same folder.
 
if you need the V4 maps i can give you the torrent and you'll get them in 1h , all the maps you need
on that gps forum you'll loose days to download them with that system they got, dont bother
i put a few cd's on the SD card today, takes a lot of time to copy
 
I managed to burn 2012 maps using the CDRWIN 5.05 at the drives full speed and it worked first disc :)

Now to try and get and sort out 2013 V5 maps lol
