Does anyone know if i can upgrade my IOR for the IOS radio?

I just have the base convenience package in my LT Trail Boss, is there a way to upgrade the infotainment to have HD Radio capabilities?

Old post, but I was looking for the GM 84489271 and it has come up as a discontinued part. Does anyone know if they have changed part numbers or if this is still possible with the 2020 trucks.

I know this has been gone over previously,but I’m curious...I just bought a 20 lt z71 and I was told factory navigation is not available without replacing entire stereo system for about $9500.. this has got to be b.s.  I do have the sd card slot on bottom of dash
