I have a hacked Curtis gpd359 GPS running on Navigon MN 7.4.0 PNA 320x240 (new SW 2310). with Maps from 2008. The software runs like a charm but the maps are getting old. I would like to update the maps to the most current Q3 2009 or Q1 2010 but wanted to ask first as sometimes new maps don't work woth older software. I will also need to update POI, Landmarks etc.
Can you please point me to the right place to get the appropriate map for my version of Navigon ?
Canada / USA.
If I need to update the software version, where do I find that ?

Much appreciated !*
