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?

Many examiners in my area will allow portable GPS as a supplement, even
during partial panel. One DE has been known to unplug it during a
simulated electrical failure, if the applicant didn't install fresh
batteries? Oh well! If the batteries are good, it's fair game. In
fact, many allow them during all but the cross country phase of a PP
checkride.

At a safety seminar, one DE explained it to me as "all available
information."
