Great question. I have read this entire post and the only option is to search for the VIN of a vehicle with the same specs as what you have installed and run that through the Uconnect firmware update site and see if it triggers an update.So question, how do you update the uconnect? Cause on my vin it won't have anything for the 7in unit.
That update would then have to be put on a USB drive and downloaded into the head unit manually.
From all of my research it seems that the 7 inch head unit does not receive many updates, if any at all. That is other than those done by the dealership which are pushed through by corporate.
The 8.4 inch head unit has more options mainly the off-road page therefore gets “routine” over the air (OTA) updates.
Someone please correct me if I am wrong.
I have been trying the above mentioned method without any success.
