I think this is pretty much up to the examiner.

On my checkride, I was allowed the full use of the radio panel the
entire flight. In my case, Garmin 295, KX155 + GS, KX170 + LOC, ADF,
LORAN, DME.

Pleasantly surprised you were allowed to use the Garmin 295 since it's not
certified for IFR flight. To me, it's a great supplement for situational
awareness, which I'd suspect your examiner felt the same way for he / she
to allow you to use it?

I didn't have an ADF in my plane, just ILS and DME, so all I could do at
the time was ILS, LOC and VOR approaches.

In my check ride, I was asked to do a VOR, ILS and a back course localizer
approach. My partial panel was a VOR approach in which my DE allowed
(encouraged) the use of my VFR Garmin for assistance in the ground track.
