Nano v3.0 won't appear in arduino/simulink support package

I have recently purchased an arduino nano v3.0 as a replacement for my uno board. I have been using Simulink to program it with the support package provided by the link below and it has been working flawlessly. It clearly states on the web site it is compatible with the nano 3.0 but when you go to tools, run on target hardware, and then options, the nano never comes up in the selction list and trying to download it as an uno or mega has been unsuccessful. If there are any tips or advice you guys can provide it is greatly appreciated.

Same problem here. I just have been able to connect with nano through Matlab/ serial port.
