5. Mount the display and reassemble the dash using the new bezel.

6. Reconnect the battery and start the vehicle.

⚠️ 4. Initial Boot Behavior

• First boot may take up to 2 minutes.

• Screen may display a black background before initializing.

• Android Auto/Apple CarPlay may take an additional minute to become available.
  

• Vehicle Acclimation Required After UBN Install:
  After completing the Uconnect 5 (UBN) installation, the vehicle may require a short acclimation period before all features become fully functional. This process can sometimes take up to 24–48 hours. During this time, some functions—such as navigation accuracy, climate control presets, or backup camera—may temporarily behave inconsistently. This is normal and typically resolves on its own once the vehicle systems fully sync with the new UBN hardware and software.

🧰 5. Common Issues & Troubleshooting

Issue: No Audio or Inconsistent Volume

• Fix: Ensure all audio connectors are properly seated.

• Fix: Perform a hard reset: Hold volume and tuner knobs for 10–15 seconds.

Issue: HVAC Controls Unresponsive

• Fix: Confirm HVAC module compatibility.

• Fix: Check the Genie Max interface DIP switch settings.

Issue: No Android Auto / Apple CarPlay

Issue: Unit Stuck on “Loading” or Black Screen

• Fix: Cycle power, verify connections.

• Fix: Try holding volume + tuner knobs for 15 seconds.
  

• Performing a Full Power Reset via Fuse Removal

  Simply disconnecting the main battery may not fully reset the modules due to residual power from the auxiliary battery (common in vehicles with Engine Stop/Start systems).

  Steps for JGC WL and Wrangler/Gladiator:
  

• Verify that all hardware is fully installed and securely connected.
• Disconnect the negative terminal of the main battery to stop primary power flow.
• Locate the fuses (Wrangler Gladiator) responsible for the head unit (F97 20A Yellow) and HVAC center stack (F105 10A Red) located in the diagram below.
  

• Locate the fuses (Jeep Grand Cherokee) responsible for the Radio (53 MICRO2 20A Yellow).
• Remove both fuses and wait approximately 10–15 minutes to allow all residual power (including from the auxiliary battery) to fully drain.
• Reconnect the negative terminal of the main battery.
• Reinstall both fuses at the same time to simultaneously restore power to the systems.

This process forces a complete reboot of the head unit and HVAC modules, allowing the vehicle to reinitialized communication with the newly installed hardware.


Jeep Wrangler/Gladiator

The Jeep Grand Cherokee WK uses two key fuses related to the radio system and associated functions:

• Radio Power Fuse: A 20 Amp yellow micro fuse located near the battery under the front passenger seat. It is enclosed in a black rubber capsule with a thick orange wire. This fuse is not in the main fuse box and can be difficult to find.

• ICS/HVAC Fuse: Fuse F49 – 10 Amp red mini fuse labeled Integrated Center Stack / Climate Control. Located in the interior fuse panel, this fuse powers the integrated center stack (ICS) module and HVAC controls, not the screen directly.

🚫 6. Grand Cherokee 10.1" UBN – No Backup Camera 

When upgrading a 2019+ New Body Grand Cherokee to the UBN 10.1", some users have reported that the backup camera does not display when shifting to reverse (no screen change).

✅ Solution:

1. Change the Genie Max DIP switch orientation to MODE 17. This is a configuration originally designed for the Wrangler/Gladiator 10.1" UBN upgrade without HVAC changes.

🔁 DIP Switch Settings – Mode 17:

This setting has resolved the issue in multiple Grand Cherokee vehicles and enabled the reverse camera view to display properly.

⚠️ Note on Off-Road Pages:

Using MODE 17 will populate Off-Road Pages, but the vehicle shown in the menu will resemble a Wrangler, not a Grand Cherokee. This is a visual anomaly only and does not affect functionality.

If a customer raises this concern:

• Inform them the feature is non-functional for their model regardless.

• The vehicle image cannot currently be changed.

• This may be addressed in a future software update.

📝 7. Additional Notes

• Trailhawk trims may eventually require a modified configuration to correct visual/functional discrepancies.

• Always confirm firmware and module compatibility before installation.

• If unsure, contact support for up-to-date Genie Max DIP switch maps.
