Sounds more like the old days of trying to fly an NDB intercept.
Correcting cross winds in your example sounds harder than actually
usnig a VOR. The reason I like airways on the GPS is because while the
clouds are wacking the crap out of you and you're jumping through busy
airspace, you can quickly turn the plane to maintain the center of the
airway. You also don't need to figure out what intersection the airway
turns at next. It sounds like Garmin IFR pilots keep an enroute very
close at hand so they can figure out where all the turns are in the
airway.

You're on the 250 radial and want to track a 070 course to the ABC VOR. Set
the CDI to 070 and turn the aircraft until the track readout shows 070. The
aircraft will (barring VOR errors) stay on the radial. If it does move,
turn the aircraft to adjust the track.

The GPS doesn't need to know about the existence of VORs or LOCs.

It doesn't help you with programming the GPS for course guidance along a
winding airway, but it's an aspect of GPS utility that many pilots seem to
ignore.
