A:AnswerYes the DriveSmart 66 and 76 use the same 17mm ball suction cup mount. For the DriveSmart devices the Traffic is received via the Drive App and a Traffic cable is not required.
A:AnswerThe suction cup has held securely for over 2 weeks. I have it mounted on my car dash. Had to attach a smooth plastic piece with foam tape to the dash to get a smooth surface for the suction cup.
