So, I just bought a Garmin nuvi50, and I have a several week road trip planned in the middle of June. We are driving to MI to attend my brother's wedding (yes I'm shooing it!!!). On the way home we are going to spend about a week along the 40/10, hitting Mammoth Caves, maybe Carlsbad Caverns, Petrified Forest, etc. I am anxious to use the GPS to its fullest. The Garmin sight offers their app called BaseCamp for trip planning, etc. I'm wondering if anyone has used this, or is there something better out there? I want ease of use first and foremost. Thanks!!!
