Today I took my Gen. III to the dealer to have the ECU flashed to update the brake programming. At the same time, I asked the tech to modify the reverse beep from the default of constant beeping in reverse to only beeping once when putting it into reverse. What a relief! They should not charge you for this. I was able to do the reverse beep modification myself in my Gen II, but I think a tech must do this modification for the Gen. III.
