just purchased a Sonic. yes it comes with XM, but this is my commuter car and I have an old roadie2 in my Subie that I'd like to install in the Sonic and transfer back when I'm driving it.
quick search turned up nothing.
curious if anyone has done this and what's needed and where you installed your unit
