Narrative:
During initial descent the captain obtained the weather in gon and they were reporting 700 broken and RNAV 23 was in use. We were on the RNAV runway 23 going into gon and the FD and ap wasn't flying the approach properly so we disconnected the ap and I flew it raw data by hand. We briefed it prior but I was relying on the captain to advise me when I could descend for the next step-down fix. We reached hirka and advised gon tower. We descended out of 2000 for 800 until 2.0 NM to RW23. We are still in the descent and the captain says you can go down to MDA of 560 and selects it in the altitude select. We reach MDA of 560 and driving to the missed approach and gon tower comes on and says check alt immediately. We went missed and tried the ILS 05 and went missed again. We ended up diverting to pvd.

Narrative: During initial descent the Captain obtained the weather in GON and they were reporting 700 BKN and RNAV 23 was in use. We were on the RNAV RWY 23 going into GON and the FD and AP wasn't flying the approach properly so we disconnected the AP and I flew it raw data by hand. We briefed it prior but I was relying on the captain to advise me when I could descend for the next step-down fix. We reached HIRKA and advised GON tower. We descended out of 2000 for 800 until 2.0 NM to RW23. We are still in the descent and the captain says you can go down to MDA of 560 and selects it in the ALT select. We reach MDA of 560 and driving to the missed approach and GON tower comes on and says check alt immediately. We went missed and tried the ILS 05 and went missed again. We ended up diverting to PVD.
