For some strange reason, the Bluetooth controls on all Hyundai vehicles are located where the sunglass holder would normally be (you can even see the door for the sunglass holder). I'm sure it saves them a couple dollars a car or something.
As far as an actual place for sunglasses, nothing springs to mind. I usually put them in a case in my messenger bag. If you have "flat" sunglasses you can try the small cubby in front of the gear shifter (above the ashtray), or you could get an inexpensive sunglass clip for the visor:
On a somewhat related note, has anyone found a good place to store change? I purchased a cheap coin holder that doesn't hold pennies (urgh!) and I have yet to find a convenient, yet concealed, spot to put it. The one I purchased looks like a less tall version of the one pictured below. I had initially thought I could remove the ashtray and put it there, and secure it with some double-stick tape, but it doesn't fit. I also tried the pop-out door pocket. I stuck it on one end, but it was too difficult to access.
Geez Hyundai, how hard would it have been to include a built-in coin holder in the center console?

I'll probably just end up throwing it all in the ashtray for lack of a better solution.
