Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, and a flathead screwdriver.
Ensure the vehicle is in a safe, well-lit area and parked with the engine off.

2. Check GPS Signal

Turn on the ignition to the accessory position.
Access the navigation system menu and check for GPS signal status.
If no signal is detected, inspect the GPS antenna located on the vehicle's roof.

3. Update Software

Connect a USB drive to a computer and download the latest navigation software from the Honda website.
Insert the USB drive into the vehicle’s USB port and follow on-screen instructions to update the system.
Ensure the vehicle is running during the update process to avoid power loss.

4. Inspect Fuses

Locate the under-dash fuse box and remove the cover.
Identify the navigation system fuse (refer to the owner’s manual).
Use a multimeter to check if the fuse is blown. If blown, replace with the same amperage rating.
