I recently purchased an 06 LR3 SE, so far I'm extremely pleased with it after the first 3k miles. One thing that I still haven't figured out yet, is what is the speaker looking thing in the middle on top of the dash? My salesman didn't even know what it was when I asked and I can't seem to find any reference to it in the manual. I have PTI and was thinking it may have something to do with that?
