C206 PLT ENGAGED AUTOPLT DEPARTING TEB. THE ACFT OVERSHOT THE ALT AND INITIATED AN INCORRECT TURN; DEVIATING FROM THE PUBLISHED DEP.

Narrative

THE INCIDENT OCCURRED UPON DEPARTING TEB ON THE RWY 24 STANDARD INSTRUMENT DEP (SID) WHILE CONDUCTING AN INSTRUMENT REFRESHER FLIGHT. I HAD FILED ONLINE AND HAD RECEIVED A SUBSTANTIALLY DIFFERENT ROUTING THAN WAS FILED OR EXPECTED FROM TEB CLRNC DELIVERY. AFTER THE CLRNC WAS RECEIVED; I ENTERED THE NEW ROUTING INTO THE GPS UNIT AND POSSIBLY ENTERED THE WRONG SID. TAXI CLRNC WAS RECEIVED AND I TAXIED TO RWY 24 AS DIRECTED. THE EXTENDED IDLE AND TAXI CAUSED A MINOR PLUG FOUL SO A CLEARING RUN-UP WAS CONDUCTED AND THIS DELAYED MY DEP. TEB TOWER WAS THEN NOTIFIED THAT I WAS READY TO DEPART AND CLRNC WAS GIVEN TO DEPART RWY 24. I HAD A NORMAL DEP AND INITIAL CLB THEN WAS HANDED OFF TO NY APCH ON THE PRE-ASSIGNED FREQUENCY. I CHANGED OVER AND ERRONEOUSLY STATED '...WITH YOU 700 FT FOR 7000 FT' TO APCH. 7000 FT WAS THE FINAL ALTITUDE AND I UNDERSTOOD THAT MY INITIAL ALTITUDE WAS TO BE 1500 FT PER THE SID EVEN THOUGH I MIS-STATED 7000 FT. I WAS HAND FLYING THE PLANE AND SET THE AUTOPLT TO AGAIN REVIEW THE SID BECAUSE I SAW A CONFLICT WITH WHAT I HAD READ VS. WHAT WAS DISPLAYED ON THE GPS SCREEN. WHEN I SET THE AUTOPLT THE ACFT BEGAN TO TURN RIGHT BEYOND THE CORRECT SID FOR TEB AND ATTEMPTED TO FLY WHAT I FEEL INCORRECT PROC. I DETECTED THE INCORRECT TURN AT ABOUT THE SAME TIME AS THE NY APCH CONTROLLED ADVISED ME TO IMMEDIATELY TURN RIGHT TO 280 DEGS IN ORDER TO MAINTAIN SEPARATION FROM OTHER ACFT. I ALSO BECAME AWARE THAT THE ACFT HAD GAINED ALTITUDE. I CONDUCTED A STEEP TURN TO COMPLY AS SOON AS POSSIBLE AND BEGAN A DSCNT BACK TO 1500 FT. ONCE ESTABLISHED ON COURSE AND ALTITUDE I WAS ADVISED TO CALL TRACON AT THE CONCLUSION OF MY FLT. THE FLT WAS THEN CONTINUED AS PLANNED WITHOUT FURTHER INCIDENT.
