Yes, there is a harness available to output Speed, but I cant think of the part number right off hand. I installed one in my GS setup, and it can be a pain depending on how hidden you want it. it has 3 or 4 different connections on the cab side, and one or two on the gps side. was fairly inexpensive, something like 125.00
