Under "preferences screen" on the digital display, I have lost the ability to select "trailer mode". It no longer appears on my display. My friend's RT has exactly the same problem! We both have had our 600 mile checkup and we think we lost this display when we were hooked up to the diagnostic computer during the 600 mile checkup. Anyway we both took our Rts into the dealer 2 weeks ago to show them the display problem and they are clueless. They have deferred to BRP but BRP has not gotten back with them. The dealer seems to think it is related to a new software update they received not long ago. However, that would mean there are other Spyders at other dealerships who have received that same update and are also losing "trailer mode". Anyone out there got the same problem?
