There is no longer a cord for the OBD. Which would sometimes have connection issues from being bent or wrapped from being tucked away for the previous model.
Only port it has is a USB C port, which is on the bottom of the unit.
Tips:
-Dremel inside the line, not outside or on the line.
-Use the sanding stone attachment for the corners, if you want to achieve the rounded look.
-Add black touch up paint as the final touch.
