    TSB: PI1380, No GPS Signal

    There is a technical service bulletin on C7 Corvettes which are unable to get a GPS signal. Thanks to help from "Suzy Cruisy," we have a copy of an actual repair order with more detailed information.

    Returning Red X issues

    It appears that there is an updated TSB related to fixing this issue. The new fix requires additional wrapping of the unshielded cables with more cable that requires wrapping. (with foil) Additionally, more cable separation is required, as well as some cable re-routing. The new software "fix" that came out in February will also be uploaded. I will keep an eye out for this newly updated TSB and post it here.
