Just to keep this thread going... After much research and several attempts to contact 3d party and OEM manufacturers, it appears 2010/2011 Terrain and Equinox both use 44-pin 29-bit GM LAN PDIM interface and there isn't a verified HD tuner solution at this time (short of swapping the entire head unit).
The one product to keep eye on is
PAC Audio ISGM571 (HD radio and iPod adapter), however after conversation with PAC Audio support rep, this unit was not tested on either equinox or the terrain and therefore it's listed as "not compatible" until proven otherwise (It is a 29bit GM LAN compatible adapter).
