I am very new to the whole GPS thing. A few months back, I picked up a NIB Garmin 76CX. I have played with it a bit and was able to load a track to it. The track worked fine, but there are no roads listed. I am guessing this is "Basemap". I would like to add something like City Navigator, so I can use this GPS to to more than follow tracks. Will I need the CN software pre-loaded on a MircoSD card, or do I need to buy the CD/DVD version? If either will work, pros and cons? -Joe
Get it on DVD, that way you can load it onto your computer. Buy another uSD chip and load the new map on that via Mapsource or MapInstall.
