Toll Transponder?
 

I hear the eTron comes with an integrated toll transponder. Have any of you tried it in lieu of an NTTA TollTag (Dallas area)?

I initialized my system and the system works in many states. I haven’t had the opportunity to use it yet at the tolls, but was confident enough to put away the old transponders.

Registered and used here in the NY Metro. I need to figure out how to get the tag number though so I can get the EV discount at the bridges and tunnels. If not I’ll have to turn it off and use the local tag.
