Using my Garmin Nuvi 2555 on my motorcycle. I keep track of my travels downloading the activity log to my desktop Mac with BaseCamp. However after two days or so the Nuvi starts to erase old data (not enough memory). So if I am out for a week I lose the first few days. Can I capture that data on my iPhone or iPad (which I take with me) and transfer it to my desktop later? Or can I change the activity log to record less info so I can store longer trips? Thanks, Taylor
