I believe the AOPA Radio nav course includes GPS and counts towards the IR(R).
Whilst the a good grasp of the basics of navigation is essential, and some are happy/derive satisfaction from just applying the basics, the modern world uses everything available.
Yes, there are many GPS devices available, but the underlying principles are the same.....sometimes RTFM is required.
