The nonadjustable wimpy beep on the Garmin is my one beef. On my upright, normal bike it is not a problem but on a recumbent, the speeds and wind noise are much higher and I cannot hear the beep when a car is approaching (Varia) or any of the warnings. I understand they needed to put the speaker on the underside of the device but did it have to be surrounded by the twist mount, too? And why no volume control? Rant over.
