I have 3m as well.
I place it on the dashport using Velcro so that I can remove from sight when not in use.
For most tolls I have no problems if I drive slowly. It will read not detected first but as I move along it will detect and off I go.
For a few tolls it will work straightaway.
I think the key is to drive real slow.
