U0485 on Chrysler by model: symptoms, diagnosis and fix

Link to this issueError Codes:U0485

Stellantis TSB 08-181-24 Rev. A (October 2024) covers specified 2022–2024 Pacifica/Voyager (RU) vehicles with Uconnect 5 NAV (8.4" or 10.1" display) and a Global Telematics Box Module. It attributes a list of symptoms — including inability to select turn-by-turn navigation, a black navigation map, blank performance pages, missing widgets, voice recognition inoperative, ghost touch on the navigation screen and the display jumping from the Media page to Home — to various software issues in the radio's current software. The remedy is an over-the-air update from U29.28 or U33.9 to U33.43.

Common Symptoms

  • Unable to select turn-by-turn navigation or navigation map black
  • Blank performance or off-road pages (rear camera works normally)
  • Widgets missing or media widget blank
  • Voice recognition or Android Auto voice recognition inoperative
  • Ghost touch on the navigation screen
  • Display switches from the Media page to the Home page

How to Fix

Check the exact radio sales code, installed software and vehicle eligibility before selecting an update. Bulletin 08-181-24 Rev. A describes an over-the-air update for specified Uconnect 5 NAV configurations; it is not a universal instruction to USB-flash every Voyager. Follow the current applicable update or diagnostic procedure. If symptoms remain, diagnose software, power, network and hardware causes rather than ruling out radio replacement solely because a flash can be completed.
