Give the people at navrepair.com a call they are the only company I found that sells replacement factory head units that fit my vehicle. I change mine out with a kit I purchase from them. But be forewarned they usually do not answer the phone and email seems the best way to get in touch with them. Don't know if they have this head unit yet but it's worth a try. But it could cost you over a grand for the upgrade. That's about what mine cost.
I stand corrected just checked my records you will have to contact https://www.infotainment.com
for the radio upgrade this is where I got the new head unit. I got the nav system activation code from navrepair for my previous radio because the dealer wanted more that double to activate the maps.
