Uconnect software version 18.45.01 is a critical update for Model Year 2013-2017 Chrysler, Dodge, Jeep, and RAM vehicles equipped with the 8.4-inch VP3/VP4 systems. Its most "solid" feature is improved system stability and compatibility for newer map updates. Key Improvements

3. Known Issues Addressed in This Version
Version 18.45.01 acted as a "patch" for several specific user complaints documented in earlier builds (such as 17.xx.xx):
- The "Black Screen" Bug: Fixed a critical error where the screen would go black and require a vehicle restart.
- Climate Control Reset: Corrected an issue where the climate control temperature settings would visually reset to "Lo" or "Hi" upon vehicle start, even if the actual temperature was different.
- SiriusXM Buffering: Improved the buffering on SiriusXM Travel Link services (fuel prices, weather, sports scores) to prevent the "No Data Available" error message.
3. CarPlay & Android Auto Stability
While CarPlay and Android Auto existed in earlier versions, they often crashed when switching apps or receiving calls. 18.45.01 significantly reduces these crashes:
- For Apple CarPlay: Reduced audio lag during phone calls; fixed screen flickering when using Google Maps.
- For Android Auto: Improved USB detection (no more “Device Not Supported” errors with Samsung Galaxy S9/Note 9).
E. Performance & "Stop/Start" Integration
- Boot Time: Slightly reduced the time it takes for the screen to become active after starting the vehicle.
- Stop/Start Memory: In Ram 1500 and certain Dodge models, this update improved the logic surrounding the ESS (Engine Stop/Start) system reset, preventing the radio from rebooting or glitching during aggressive automatic engine restarts.
