Adjust and Secure Infotainment Coaxial Cable Shield

Safety Precaution: Ensure the vehicle ignition is turned completely off and the key is removed before beginning work to prevent electrical shorts.

1. Carefully remove the trim panels surrounding the infotainment display to gain access to the rear of the head unit.
2. Locate the coaxial cable connection module behind the display unit.
3. Utilize the specialized Hyundai-approved adjustment tool to compress or resize the cable shield to ensure a tighter, more secure physical connection.
4. Firmly reseat the coaxial cable into the infotainment module, ensuring it clicks into place and is free from any tension or excessive slack.
5. Reinstall all trim panels and power on the vehicle to confirm the screen remains stable during operation.
6. Verify the fix by lightly tapping the area near the display or driving over uneven surfaces to ensure the signal no longer drops or flickers.
