Jennifer got me a GPSMap 78S for my birthday and I'm wondering if you guys can give me a little advice. I have a Zumo 550 for my street bike and it's fairly idiot proof. But the 78 comes preloaded with only a base map. I do have a 4GB microsd card for storage.
Any suggestions about what map(s) I need to get so this will help for numbered trails and regular roads? Or rather, what would you do if it was new to you and you dual sported a lot.
