Ok, I went to the my dealer and had to have my truck smoged. Welcome to Cali........ Had the tech re-set the tire size for the new tires. The WiTech listed specific tire manufactures and their sizes. The Pro Comps ( A/T, 305x60x18 ) that I bought were not listed. Guessed and got it to within one mile a hour........The tech said there was three updates and I told him, update the truck. That was a mistake, now my Edge Insight will not work ? not sure if it is the Insight or the OBD-2 and something with the communication between the two ? The Insight comes on and there is no data. I will call Edge tomorrow. I tired to update it on line and it is not playing nice, will not connect through Fussion ? The tech also tried to change the TMPS setting too and could not, I copied and pasted and printed the forum's how to and he gave it a real college try. They have the latest WiTech updates ? Boy I miss not having the Insight !
