Since we''ve used the Yeoman Navigator Pro for a few years, I''ve got a passing familiarity with the Sport. To be sure, it was designed with the intent of being linked to a
GPS as that''s its one and only claim: it allows one to interface
GPS-accurate data to paper
charts. IME Yeoman had
Garmin devices primarily in mind when designing their software; you should find the products fully compatible. However, you may need the relevant manual when hooking up the NMEA data wires from the
GPS...or you can just experiment a bit. I believe that Weems & Plath in Annapolis, MD still represents Yeoman in the U.S.
