Is there a way to determine the current software on my 2014 Silverado 1500? I have been having trouble with it and my iPhone. It is playing somewhere but not over the radio and it will not show up as connected. Often I have to delete everything and start all over again. I found a list of updates on line but I don’t know how to update it let along find what version is on the truck. This is the open source site https://oss.bosch-cm.com/gm.html It’s just the stock 3” radio. Thanks in advance, Jon
