I'm planning a trip to Maggie Valley, NC from S. Florida. I checked over my route and matched it up with google maps since this GPS has burned me before. The tom tom tells me to take HW I26 West from I95 till I get to HW I40 but I must get off at exit 31B to get to I40. There is no exit 31B just 32B based on what google maps tells me. Can someone in this area confirm who I should believe and if this is a major mistake on the gps that could have me going off road or something.
