Upon initial contact with GSO TRACON; the pilot not flying informed the Controller we were requesting a Visual Approach to Runway 24 at BUY. As we got closer to BUY; the cloud deck below us became more solid and a quick check with the AWOS now reported a 1;900 foot ceiling. Since 1;900 FT is below the MVA; the pilot not flying informed the Controller [that] we [were] requesting vectors for the RNAV (GPS) RWY 24 and direct to DALSY which is the IF/IAF. GSO TRACON issued a Right Turn direct DALSY. The pilot not flying informed the Controller DALSY is left of our aircraft position. The Controller stated direct DALSY is a right turn. The pilot not flying stated we have three independent GPS sources and they are showing DALSY on the left side of the aircraft. The Controller disagreed with our indications and restated DALSY is on our right side! Rather than disputing this any further and for the safety of the flight; I elected to execute the ILS Y RWY 6 approach and had the pilot not flying request vectors for the approach. The Controller vectored our aircraft to KAKLE the IF/IAF which was on the right side of the aircraft. I flew the ILS Y 6 approach and circled to Runway 24 due to the surface winds exceeding our maximum tailwind component for landing on Runway 6. The flight landed without incident. We confirmed with our passengers that all electronic devices were either OFF or in AIRPLANE MODE. The pilot not flying and I debriefed the approach scenario. We agreed that it appeared the information the GSO TRACON Controller was reading from his radar display was 180 degrees out of phase from our actual aircraft position.
BE20 Captain requests direct DALSY for the RNAV approach to BUY. ATC issues a right turn direct but the Captain sees the fix as to the left of the aircraft. ATC disagrees and the Captain requests the ILS to Runway 6 and circle to 24; which is accomplished without issue.
