It was nice that the intermediate version beeped when getting pinged; the new flex version (with number of riders switch) is silent again. Maybe it's time to hack a tone into it.
The new Flex transponder (with 1,2,3 switch) does beep for me when passing a bridge toll port (84, 92 etc), not on the highway 101 lane.
Ah, that's interesting. I've never heard a beep from any of my transponders, including crossing bridges. Is yours the "gumstick" one? (Thin rectangular one). A beep would be a step in the right direction (but doesn't solve my other grievances).
I have a gumstick Flex from 2019 and it beeps.
Mine beeps but it is an ancient model that is quite large (maybe 3 inches by 3 inches - square)
I have a new southern California FasTrak switchable, and it does not beep (it's not supposed to, either, per the toll agency: no battery, no piezo).
How "new" is it? The new ones are not supposed to beep.
