Well, unfortunately, the phone number provided by DodgeCares wasn't all that helpful. The people at that number said they don't have anything to do with the Dodge Journey Nav system. They did however connect him with the people at a place called Dodge Uconnect who tried over the phone to help him out. They went through a few procedures, none of which worked. They ended up opening up a service ticket with the local dealer for him to try to get them to fix it. I think you know where that is headed. In the mean time, I am going to prepare to try a couple of other things to get it talking in English again.
