Hello,

My Nuvi 310 currently displays the following when I select map info:

City Navigator Australia NT 2009
[1] MAREE, SA, QUILPIE, QLD, ROMA, Qld

and

City Navigator Australia NT 2008
[1] ALL

The files in my Garmin folder are:

gmapbmap.img
gmapprom.img
gmapprom.sum
gmapsupp.img

When I was in Australia last week I received a warning that the maps hadn't been updated for more than 12 months and they should be updated.

This looks like the same maps that I have though.

Also. I bought this unit second hand the map entries were already in there so I have no idea whether I need the two map selections or not. The first one appears to be a custom map or route for Queensland. Should anything be deleted from my Garmin folder to slim it down?

Thanks
