Hi All.
We really haven't had any troubles at all over many many years of traveling with a TOM-TOM-ONE GPS, and also for many, many years of using a "Delorme GPS SYSTEM, that you use on your Laptop Computer.
Later on we even up-grade to the Newest 5 inch TOM-TOM-ONE GPS SYSTEMS. So far in all of these years, we have never been taken down any wrong roads or any wrong turns. We made everyone of our "Destanations Trouble Free"
We still use our first "Tom-tom-One", in our "Toad" and use the 5 inch one in the Motorhome. Works out great for use. Plus we have always had up-graded newest "Road Atlas's with us too. Not to bad for being an "Traveler" an "RV'er", and a Boon-Dockers for the past 46+ years.
We also have never "Broken Down" or have ever had a "Flat Tire". I have done all of my own work on every RV we have owned in all of theses years, and everything else we hqve owned too. Good Luck to All. Happy Travels. Dan & Jill & our two Small "Yorkie Kids" who love to travel as much as we do.
