I have been considering a Hypertech, upon reading the install instructions it reports you MUST remove the fuses for the NAV system, SAT radio, and remote start. I cannot find these fuses identified in the manual or the fuses box lid. Also, I am going to tow this vehicle behind a RV and have to disconnect the battery when I tow. Will I have to pull the fuses (when I find them) or will the LOD do the same thing?
