I fully agree, do not accept a Nav position. I made that mistake many years ago and it took me a helluva longtime to get out of it. Only now after 8000hrs of Nav and FE time, 40yrs of age and a lot of work as a pilot am I upgrading to CAPT with my airline. The usual line from the recruiter is that Nav is the fastest road to the frontseat. that's BS...

Good luck,
