Thanks for update. How on earth do they think the OTA is possible when you look at all the conditions (SOC, battery voltage, profile mode, etc)? If OTA was so much better, why not do it that way at the dealer? They should be able to force an update through secret commands.
I watched a tech try to do it mobile and it looked primitive. = downloaded to tool, build USB key, then insert in car USB and then start update. In my case, it failed to recogize the key and the tech stopped. I considered that as a blessing. He was able to get window fix and the GWN done but balked on the APIM.
I have noticed it takes MINUTES for the vehicle to recognize a USB key (like a music USB),
