Garmin Drivesmart 61LMT

By Garmin Nuvicam has been a real disappointment, battery dies is a few weeks if not connected power and will only power unit for about 10 minutes when fully charged. Now the unit will not connect to my mac. Instead of connect it beeps and goes into drive mode. The problem is intermittent, I got it to go it to connect two times today but won't connect now. I have changed cables, restarted the computer, did a factory reset on the Nuvicam.

My question is on the Drivesmart 61LMT. Can you upload routes from basecamp. It has wifi connect for updates and Garmin does not mention Garmin Express or BaseCamp.
