So I picked up the new Garmin 530 and I really like it. I have my shimano Ultegra di2 connected to it so I can see my battery level and get alerts. I have the bike shifting in synchro mode and I really like the alert it throws when the next shift will result in a front chainring shift. However, it also randomly gives me alerts, with a corresponding beep, that I am in "Shift Mode E2". This is really annoying and pisses me off. I do not care for my computer to tell me what shift mode I am in. I cannot change the shift more on the fly so I really don't need to know in the middle of the ride.

Does anyone know how to turn this specific alert off? Is there something about my setup that could be causing it to be triggered? As I said, it appears at random as best I can tell. Really frustrated with this one thing, otherwise I really like the 530.
