The exit numbers for the interstate highways in Massachusetts Turnpike changed at least a year ago from sequential to mileage-based, but Garmin still hasn't updated the Express maps to reflect the change. I have a Nuvi 68LMT. What are Garmin's plans, if any, to update the exit numbers? As it stands now, I can not recommend Garmin GPS products to anyone until the Garmin maps show the correct exit numbers.
