Hello Forum!!
I realize this thread is getting a little old but I did not find any follow up when searching.
I have a 2018 Colorado and after replacing the battery I have experienced the same problem as the original poster (and previous post).
Radio shows WiFi connected but the Apps say no internet ... check WiFI ... etc ...
I was wondering what the final resolution was?? Did you guys get another radio from the dealer ... just living without it ... or what??
Thanks in advance ... (posting as a guest) ... ?
