I have a 2017 Accord Touring V6. Just got it so I have a temp plate. Last night on Ohio Turnpike, the toll gates opened automatically. I had no EZ Pass nor did I pull a ticket. Looks like over the rearview mirror there is a black unit that is not an add on. I stopped at the dealer and they said there is no such thing as a built in EZ pass. Not sure how the gates opened but also don't want to ignore and in 6 months get a huge toll bill. I e-mailed the sales person who sold me the car to see if previous owners put something in there. It's a complete mystery to me. Any advice or direction would be appreciated. I have not yet read manual because I just got the vehicle. Thank you.
