No one cares how you get into the hold. Someone in this thread said that if their GPS won’t direct their hold entry they won’t hold...that would require declaring an emergency and scrutiny from FAA if you’re unable (or unwilling) to comply with an ATC instruction...so be careful with that move. If you file an IFR flight plan, the expectation is that you can follow basic ATC instructions (like navigating into a hold). If your navigation system is malfunctioning, that may be an emergency.
If terrain isn’t a factor, ATC isn’t watching your entry and as long as you’re more or less in the vicinity of the holding fix, the objective of the hold is being met. On the other hand, if you’re in a non-radar environment, botching the hold entry could potentially be fatal if you’re operating near terrain.
I once issued the same holding instructions to two 737s, same airline. One did the hold I issued, the other did the 180 degree reciprocal of the instruction. Since The point of the hold was to wait for weather to pass, and I just wanted them to stay close to a particular VOR, it didn’t matter, and I didn’t say anything. ATC isn’t out to get anyone for minor infractions of no consequence. If you need a vector to get yourself set up, ask for it.
