Nice thread. Fl1ngfrog has summed it nicely. Accurate balanced flying is the key. Gps is the practical every day solution once you have a licence. The addition of being able to demonstrate basic vor use on the skill test is an advance. Our fleet has garmin 430 coupled to the number 1 obs. Use of this in both vor and gps mode is covered in the pre test revision phase of the syllabus.
Just bear in mind the op was asking for help whilst learning.
