Arch Angelos if you can do those basic things that's all you need.
Also wrt:
"I just don't want the ATO to switch it off completely since I am not "approved" to use it,"
I suggest you have a read of AIP ENR 19.2.1 specifically Note 2
There also used to be a section in AIP about the use of GNSS for VFR but I can't seem to find it. Anyone?
