2017 Ram 1500. Updated the software no issues. Maps were out of date, so I paid 150 to get the new maps. Installed and there were not issues, until I went to back up. When I put the truck in reverse, the camera was not showing correctly many lines and no picture. I called the Map company Here Navigation that sent the map. They said they could not do anything, I should take to the dealer. I asked will I have to pay and they said yes. I asked why as this was caused by their upgrade, they could not respond. got the number to Uconnect at Dodge and they said the same thing. How should I be held responsible to pay for an issue that was caused by the MAPS company and or UCONNECT. Can anybody help? Thanks
