Filed out en route to destination. Clearance Delivery assigned 'vectors; on departure climb and maintain 5;000 FT; 17;000 FT in ten; on departure fly heading 010; etc....' I read back filed route. Upon being handed off to approach; and given vectors; I was told to fly direct to KRMSN. I told ATC not on flight planned route. After some vectors; I was told it was on the arrival. I searched the NACO approach plate and after some searching found KRMSN fix. Clutter on arrival plate seemed to worsen situation. Also; I believe that the fact that the EA50 FMS inability to add arrivals without transition might have complicated situation. In an effort to add certain transitions; this leads pilots to add transitions that are not going to be flown in an effort to shorten the list of way points. For example; if filing FINGR.FINGR4 the shortest transition is BYP.FINGR4; so adding that to a filed FINGR.FINGR4 adds the least amount of fixes to FMS. During flight; it is up to the pilots to remember to sequence the FMS (this is not the case in systems such as the G1000). That was entered into the FMS and might have led to believe it was near FINGR. I believe that if Clearance Delivery was intending to give me the IRW.FINGR4 as the transition (that is where KRMSN is located) they should have stated in the initial clearance: 'Cleared via the FINGR4; IRW transition....'
An EA50 pilot had difficulty entering the KRMSN waypoint in the FMS because it was on the FINGR 4 Arrival IRW transition; which was not on his route of flight and the FMS design did not allow an arrival without a transition.
