If you get something that sends a signal, cell phone, wifi, whatever, it messes with the navigation instruments. Specifically when navigating off of the VOR. If you hold a device up to the VOR on the instrument panel or near the antenna it throws it completely off and makes it useless. Most planes usually navigate using GPS but some times they have to use the VORs and if someone decides to be a rebel when they do this, well, you better hope you are not flying a VOR approach to minimums in bad weather.
