A:AnswerIn reverse order: Yes, you can mount it on your windshield, which is where mine is mounted. It comes with everything you'd need to do that.
The model is portable, but I believe it only holds a 2 hour charge. So yes, you can switch it to walking directions and carry it with you, but if you're going to be gone longer than 2 hours, you'd need to bring the charging cord.
