Navi Sirius

Is there a single DIN in dash navigation system that will allow me to use Sirius and steering wheel controls?

I am planning on buying a new Elantra and would like to know if there are any single DIN sized Navi systems that I can use with the steering wheel controls and Sirius radio?

There are numerous radios that will work for you. Pioneer makes a few models the AVIC N3, N4, Kenwood has a few models KVT-719dvd , and also the JVC din sized nav KD-NX5000 . You will need to purchase a steering wheel interface to make the controls still work and the Sirius box for the sat radio.
