Navigation

[15bighorn]

Long story short had to pull my 8.4 out for about an hour, plugged it back in and now my navigation is way off and my time, it’s constantly telling me I’m in Maryland when I’m in Delaware and says I’m going south when I’m going north I’ve been all over the internet with no luck, I have alfaobd if I can use that to fix it but I’m not sure, any help would be awesome

First, take battery cables off and let truck sit a bit, try turning things on to discharge any capacitors. Then hook battery back up and try running truck on and off a few times over a couple hours. This may reset everything for you.
