I have been trying since early November to update the software with zero results. Radio locks up, GPS don't work, back up camera don't work. The online directions left a lot to be desired. Park truck, lock, take keys at least 75 feet away. Didn't work, did update with tech support on phone, didn't work. Took truck to dealer, spent two hours waiting, didn't work. Came back week later after they updated their update, spent two hours waiting, still didn't work. Dealer says updated thumb drive will arrive in mail. Week later I am still waiting. I will never spend any money updating the GPS or the UConnect subscription. At its best the GPS was marginal and the cost of upgrades will buy a very good Garmin GPS with free updates. The UConnect features are not cost effective. I really like the Eco Diesel for power and mileage but this software issue really cools the fire.
