This is probably what I would go for. I'm probably not going to do it, and I think I would have to get it programmed too.
Looks like just a pipe dream
I know @GTPprix said IOR 8" variants exist. I'm pretty sure this is the 8" screen radio.
I have a front camera with the LTZ grille I bought and installed.
I'll have to scan the QR code on my door to see the exact radio I have. If it's too expensive to do, which it sounds like it may be if I need all of the hardware and software programming done. Just thought since I bought a grille with the camera, i'd put it to use.
