Black square King Air no green cdi showing on attitude indicator on approach

Hello, I recently started flying the black square king air.

for some reason on RNAV approaches I don’t get the green trapezoid CDI on the bottom of the attitude indicator. I only get the Glideslope on the left side of the indicator.

While it’s okay if I’m flying the approach with auto pilot if I want to hand fly the rnav approach I’d have to look at other instruments or the Garmin displays to get the course deviation.

Anyone know how to solve this

Have you tried an ILS approach? I seem to remember a previous discussion about some of these ADI units only giving deviation for ILS.

Have not tried ILS, however I have seen YouTube videos where people are doing RNAV approaches with same aircraft and they do have the green trapezoid cdi indicating on their attitude indicator
