U0485 on Chrysler by model: symptoms, diagnosis and fix

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.
