On a long cross country this past weekend, I noticed the blue arrow showing the direction of flight (when turned on) was pointing slightly (~5 deg) off the actual course. What was stranger was when switching sectionals, the error went from a left of course error to right of course. Previously, I've found the arrow to be of great use when flying approaches, but the slight off-set was getting to be annoying. It clearly was an error, as I was right on the correct track, with the numerical bearing info showing everything lined up. Anyone else notice this?
