Well, I do know for a fact that the red needles' IPC has outdated software from the factory that would make the speed limit sign disappear each ignition cycle.Yeah.. I don't know... I looked in to the TSB myself and I never found documents and didn't know it is the IPC problem.
Maybe it is because the car is a 2018 leftover LOL.
It is my understanding that there is no fix for this. I only turn it on for long road trips. Ironically, this is the only time I use WAZE, too. So I either have no speed sign, or two.Well, I do know for a fact that the red needles' IPC has outdated software from the factory that would make the speed limit sign disappear each ignition cycle.
It looks like we had similar problem. Mine won't work even on 22.9 until they programmed the ipc.My car is at the dealer service department now having a "USB update" (whatever that is) that was going to take four hours to complete. I'd already had the 22.9 update but the speed limit display was still blank. Today, they replaced the SD card. No go - still blank. Thus, this latest "USB update". Service writer said that if this doesn't work, they'll contact GM tech for further solutions. I haven't tried the "reset all" yet - which of the 3 resets do I need to select? The only other thing would be replace the instrument cluster (which at least one person on this forum has had done).
Yesterday, one of my re-set stations on was greyed-out. Only looking at page 1 of presets, but I just tuned to that station, pushed and held where it was greyed-out, and it re-set. It was just one, but it did re-set.Anyone still having this problem, they have a new 22.10 update
