Definitely aftermarket. And what about that doohickey on the left side of the steering column in pic #2?
aftermarket bluetooth microphone? and maybe the thing on the left is an activation button for said bluetooth?
The think on the left appears to be the GPS antenna; looks just like the eBay image in this link: GPS Antenna for Toyota NSDN W59 NSDN W60 NSZN W60 NSZN W61 NSZN W62 NSZN W63D | eBay The thing on top is likely a microphone. If you search around, it seems some people have figured out a hack to get a non-Japan Map working on the Japanese GPS head unit. That being said, I would be cautious, as people on the Internet can say and promise anything. Good luck and enjoy your car.
