Narrative:

Approaching nassau international, ZMA informed us that nassau approach radar was OTS and vectored us off our filed route -- BR63V onto BR55V. Upon switching to nassau approach, they told us to hold at melon intersection which is on BR63V. After some conversation with approach, we clarified that we were on BR55V as directed by ZMA and nowhere near melon intersection. Nassau approach told us to continue. At 9 DME from the zqa VOR on BR55V, we inquired as to nassau approach control's intention. They asked to hold at prune intersection, a point we were beyond by 21 NM. Nassau then told us to continue to the VOR and track outbound on the 140 degree radial for 15 NM. We did so, and subsequently flew the VOR-DME approach to runway 32 without incident. There was no traffic conflict, and conditions were VMC, however, the potential was certainly there. Clearly a miscom between ZMA and nassau approach had occurred, putting the nassau controller's understanding of our position woefully behind our actual position. From my perspective, a holding clearance in ZMA prior to handoff would have been the safest course of action -- allowing a much more positive fix of our position prior to clearing us into the non radar controller's airspace.

Title: E120 FLT ENCOUNTER RTE AND COORD XFER BREAKDOWN BTWN ZMA AND MYNA AAC WHILE ENRTE MYNN.

Narrative: APCHING NASSAU INTL, ZMA INFORMED US THAT NASSAU APCH RADAR WAS OTS AND VECTORED US OFF OUR FILED RTE -- BR63V ONTO BR55V. UPON SWITCHING TO NASSAU APCH, THEY TOLD US TO HOLD AT MELON INTXN WHICH IS ON BR63V. AFTER SOME CONVERSATION WITH APCH, WE CLARIFIED THAT WE WERE ON BR55V AS DIRECTED BY ZMA AND NOWHERE NEAR MELON INTXN. NASSAU APCH TOLD US TO CONTINUE. AT 9 DME FROM THE ZQA VOR ON BR55V, WE INQUIRED AS TO NASSAU APCH CTL'S INTENTION. THEY ASKED TO HOLD AT PRUNE INTXN, A POINT WE WERE BEYOND BY 21 NM. NASSAU THEN TOLD US TO CONTINUE TO THE VOR AND TRACK OUTBOUND ON THE 140 DEG RADIAL FOR 15 NM. WE DID SO, AND SUBSEQUENTLY FLEW THE VOR-DME APCH TO RWY 32 WITHOUT INCIDENT. THERE WAS NO TFC CONFLICT, AND CONDITIONS WERE VMC, HOWEVER, THE POTENTIAL WAS CERTAINLY THERE. CLRLY A MISCOM BTWN ZMA AND NASSAU APCH HAD OCCURRED, PUTTING THE NASSAU CTLR'S UNDERSTANDING OF OUR POS WOEFULLY BEHIND OUR ACTUAL POS. FROM MY PERSPECTIVE, A HOLDING CLRNC IN ZMA PRIOR TO HDOF WOULD HAVE BEEN THE SAFEST COURSE OF ACTION -- ALLOWING A MUCH MORE POSITIVE FIX OF OUR POS PRIOR TO CLRING US INTO THE NON RADAR CTLR'S AIRSPACE.
