SW03ES,
Thanks for your help. I have read many of your postings on this forum. Can't wait, will pick up the vehicle tomorrow. I will experiment and put my EZ-Pass by the driver door handle well and also in the center storage compartment and see if the sensors picks it up as I go through various tolls. If the green "go" light don't come on then I will just have to put the tag up on the dash. Hopefully I will be able to locate a ideal place so that I won't have to mount it on the window behind the rear view mirror.
I will have a lot of reading, owner's manual, tomorrow night. Baby, it's going to be a exciting weekend.
Thanks again for your help on behalf the the entire Lexus forum.
