When I bought my 2011 Land Cruiser last year it did not come with headphones. I got the remote which works nice and the entire entertainment system seems to work well. So I was thinking about buying wireless headphones from the Toyota Dealer. I found these but it says "this part may fit". Question is: did the 2011 have wireless technology for the entertainment system or is it only 3.5mm plug in. I can't find the answer in the owners manual and before I call the dealer I thought to try here first.
