Drivesmart 71 EX or Drivesmart 76

 

I am going to add another Garmin for my second car.
I am finding it impossible to see a direct comparison between the Drivesmart 71 and 76! Has anyone had both or had problems with one or the other?

The only differences I see so far is the 76 has a traffic cable. That would account for the $69 difference.
