Hi guys im a total noob and need some help with my new gps system I received.

I currently have "Canada83_NT_2011.Q2_111004" for maps and "Canada_NT_2011.Q2_110721" for pois. They seem to be out of date and I've looked through the forums and seen alot of new maps and pois.

My problem is im not too sure which files I should update with. Can anyone please help me ???
