No, I don't have the mark Levison audio system. The system I have did come factory however. My 2006 GX has it. My 2007 GX does not. It's simply refered to as the Rear Audio System. It is controled with an Infer Red remote. Lexus part number 86170-34010. I had to buy one of those too. I'm going to stop in walmart today and read some packages. I'd like to keep the Lexus name, however, if this doesn't work, I'd be wasting money.
I'll let you know.
UPDATE -- YES, I AQUIRED AN INEXPENSIVE PAIR OF IR WIRELESS HEADPHONES, AND THEY WORK LIKE A CHARM. IF YOU HAVE A REAR AUDIO SYSTEM (NOT A dvd, AS WE KNOW THE dvd HAS WIRELESS CAPABILITIES.) BUT RATHER JUST THE RSAS, THEN YOU DO HAVE THE ABILITY TO USE IR WIRESLESS HEADPHONES. I purcahsed mine on ebay. $36 including shipping. I ordered a pair of Lexus ones for $90 however, the order was cancelled due to the product not being available. I'm thankful for that as the $36 work great. I did not find a set at my local walmart.
Can you post the name and part number?
Sorry I didn't get back to you sooner. If you search the item number in ebay, you'll be taken to the one I purchased. It works flawlessly.
