They all have warts but after dropping mine on its face last year and needing it desperately that day we traveled by car over 100 miles to replace it. Having so many outstanding features that are easy to get to makes life on the road much easier. If you are planning a new route it is always good to cross check and if you have good internet going to google earth can really ease the pain by giving you a visual of the places you need to turn,. I have even printed them out in the past.
The broken gps now has a new screen and is my backup. I am an electronic tech so replacing it was easy.
Buy a good Ram Mount and get it just above the dash so reading it does not take your eyes off the road.
