Well, it has been a couple of weeks since my upgrade and after speaking with the dealer, Guardian, Uconnect, watching many videos, which all display an inactive mic icon in the Uconnect Nav onscreen search line, I have decided it just isn't worth all this trouble. I will continue to use Send 'n Go on my phone to send my destination to the truck to get a correct mapping to destination. JDGRN77 has the best advice and that is to back up your present installation before doing the upgrade so hopefully you can return to the previous version.
I think the ability to use the onscreen mic to do an online search for destinations is not the norm. They never speak of doing this in the videos and none of the videos show the mic to be active. My advice to Uconnect is to figure out this problem because the online search is lightyears ahead of the address search function. In my area if you use an address for mapping you may get close but I have been used to door to door with online destination mapping.
Side note: I used Android Auto to map my destination back home from delivering a bull. When I got home, I traveled past my normal parking place at the house and went to the barn to leave the stock trailer. I received an inquiry from Google asking if this was the most used entrance to my destination? Google recognized I stopped in a different spot and they wanted to know which is the correct mapping location. I'm not sure I want to be tracked this closely, but it is an amazing technology.
The onscreen mic using Android Auto is active. Before the Uconnect Update the Uconnect Nav onscreen mic was active.....
