Please help me choose the best option for my business.\n\nI own a mobile pet grooming business that operates 4 vans. Each van driver thru a metropolitan area and makes approximately 6 stops per day in different addresses. Throughout the past few years I would purchase whichever gps I would find without much thought involved, but I have come to the realization that Traffic data can really optimize my business and make it more efficient. Once I started researching this field, I concluded that TomTom is the king of life traffic which is my goal. So here are my questions:\n\n1)is go 600 much more sturdy than go 60s?\n2)can the 4 units that I purchase be under my single company user name and passwords?\n3)can all my employees input my user name and password in the my drive app in their phone and use them at the same time (using separate units).\n4)after each appt, do they have to log back in to the my drive app, or does it run in the background all day?\n\n\nMy hope is that each employee would pair the phone to the gps in the morning and not worry about it the rest of the day, without any additional work (after each appt which usually lasts 2 hours. is that realistic?\n\nThank you so much for reading this! Any thoughts will be much appreciated!
