I have this same problem in my new 2025 Silverado 1500 RST. The build date of the truck was December 16th with IOK radio version Y172. On December 19th a bulletin went out to update to Y176 version of the software that includes fixes for bluetooth crackling during phone calls. I just had the dealer update my software to Y176, and unfortunately I still have issues, although not quite as bad. It's still unstable and is going to hinder my ability to drive during a work meeting on Zoom (since it uses phone call connection). The audio still drops out but it's a much faster reconnection time (1-2 seconds) on Y176 as compared to Y172 that was like 7 seconds during a drop out.
Users on other forums reported that being updated to Y175 fixed their audio issues, so I wonder if Y176 re-introduced previous issues or the dealer didn't do the right procedure after updating the software on mine (in case any resets needed to happen).
edit: I have a Garmin watch. I'll try to disconnect that next time I'm in the truck and see if it's better.
