Dodge/Jeep/Chrysler NAV Radio Repair

Dodge/Jeep/Chrysler NAV Radio Repair Troubleshooting Guide

Important: Use this guide if you reinstalled your repaired Uconnect touchscreen display and the problem is still happening.
Important: Please do not open/disassemble the unit—use these vehicle-side checks only.

• Step 1: Confirm the exact symptom
  • Touch doesn’t respond / delayed response
  • Ghost touch / random presses
  • Screen is black/blank but radio may still have sound
  • Reboots, freezes on logo, or loops during startup
  • Flicker/lines/white screen/intermittent image
• Step 2: Confirm you installed the correct part
  • Verify you reinstalled the display/touchscreen (not the radio “brain,” amplifier, or separate infotainment module)
  • Confirm connectors are fully seated and the lock tabs are engaged
  • If the vehicle had prior radio work, confirm the screen type matches the vehicle’s Uconnect version and trim
• Step 3: Do a safe reset/power cycle
  • Key off, open/close driver door, wait 2–3 minutes, then restart
  • If the screen only returns after a full power cycle, suspect a wake/enable or power feed issue (vehicle-side)
• Step 4: Reseat connectors and inspect terminals
  • Unplug/replug the screen connectors and confirm no pins are bent or pushed back
  • Check for corrosion/moisture in the connector and at the screen mounting area
  • If touching/moving the harness changes the symptom, suspect poor terminal tension or a harness fault
• Step 5: Check power supply stability and fuses
  • Verify battery/charging health (low voltage commonly causes rebooting/blank display)
  • Check infotainment-related fuses (radio/infotainment/display/USB) and confirm they have power in the correct key positions
  • If the issue happens during crank, retest with a strong battery or jump support connected
• Step 6: Separate “touch issue” vs “video/backlight issue”
  • Touch-only problems (ghost touch/no touch but image is fine) usually point to touch layer/grounding/connector seating
  • Image problems (black screen/flicker/lines) often point to screen power/backlight/video signal or upstream module output
• Step 7: Scan for codes and network communication faults
  • Scan for radio/infotainment and communication codes (lost comm, internal fault, config mismatch)
  • If multiple modules show lost communication, address vehicle-side power/ground/CAN issues first
• Step 8: If the issue started after recent work
  • Re-check anything recently touched (battery disconnect, radio swap, dash removal, accessory install)
  • Aftermarket splices (remote start, alarms, audio upgrades) near infotainment wiring commonly cause intermittent Uconnect screen issues
