My EFIS 40 HSI has gone out and I’m going to have to do some upgrades. At minimum I’m going to replace #1 com and nav with Garmin GTN 650 and replace HSI with Garmin GI 275. my question is can I keep the KI 256 Attitude indicator with flight director to drive the autopilot? And if so would I be losing any autopilot functions? I know dual 275 is probably the way to go but I’m trying to stay within a budget. The attitude indicator and autopilot are working great at the moment. Thanks for any input

Thank you all for the great information. This group is awesome.

Thanks for the quick reply. I will look it up. I will get the model number next trip to the hangar but it will be several days.

Any idea what I need here to seal the edges around the heating element on the prop? thanks in advance
