Update: I've worked with Vanku customer service and after replacing the unit, the replacement seems much sturdier. Not sure if there was a difference in firmware or what. Their support is pretty good and the device is pretty feature rich for the price. This gives you a lot more functionality than more expensive established brands like Alpine or Kenwood. I haven't had much luck with the SD card slot, so I just plugged a 32GB USB drive into one of the two available USB ports and it seems to work more reliably, as others have noted.
