Asked the dealer today if there were any updates for the Navigation on my 16 FiST. Service writer said he would get back to me, i asked if they have to hook anything up to the OBD2 connector to let me know first. First i don't want them finding out i have a tune on it, ill uninstall the tune before i take it in anyways. Second if they have to update the ECU/Nav system will it affect me reconnecting my Accessport?
