I did this update from Nov and my radio is working worse than before. I use an iPhone 7 and I can not use voice control to make a call but I was able to use voice control to make a call if the person was listed in my favorites. Now my voice control does not recognize my favorites either. What a pile of junk the Uconnect system is in the journey. It makes me upset that they have had a newer system out and installed it in other vehicles such as the Jeep Cherokee and Dodge Durango. But kept installing the inferior system in the journey. when asked about getting it swapped when my unit completely failed and need replaced. I was told they cant because of the wiring harness. I was told they are about to launch a large update to our 8.4 system relatively soon. But I'll believe it when i see it.
