Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) France Autoroute Toll Tag on CX

Not in France nor a CX owner but my Plus 4 has (I assume) a similar screen.
The tag only works when you hold it over the screen if the roof is down or out of the window when it rains.
I have had the tag for some time & find it saves a lot of time on the busy auturoutes.
