Yes it can, but it probably won't with this generation of stuff. Proposed frequency emmissions from future electronic devices might have a more severe effect on navigation equipment.

I've sat three feet from the avionics in a small jet that I'm flying with no effect.

Apparently there have been some problems with inertial navigation system alignments before, but it is not a huge problem. However, unlike the highway, you can't just pull over and fix it.
