Navigation erros and keyless entry problems

[John-Dennis]

I have recently been experiencing errors with my 2016 8.4 navigation. The coordinates are always several miles off. I also am having intermittent problems with my keyless entry which can be temporarily resolved by using the mechanical key to open the door and then starting the truck normally using the key. This unfortunately sets off the alarm until the engine is started.

How are the 8.4 radio, the navigation, the keyless entry, and the chassis computer related?

Have you checked to make sure your software of radio is up to date? Have you installed map updates as well? Did you try resetting your radio? Do all of the above and then see if that fixes things. There are threads on here for all of that, do a search for each one.

Good luck.

Perhaps you are working on two separate problems that just happened to happen close to the same time.

How is your battery?

Radio issues are likely unrelated and due to a failed or failing internal wireless aircard or a faulty rooftop antenna.
