Chester, I checked the Garmin site and they do not mention an antenna port, which I would prefer myself. They also don't show any cables or external antenna as accessories so I would be surprised it if has them. It does support a back up camera on the 7" screen.
It does support Smartphone Link for Android which allows the gps to use your phone as a data connection to access Garmin Live Services which includes severe weather alerts, radar images, local weather (free), live traffic (subscription), traffic cameras (free), fuel prices (free), etc.
