How to Remove the Navigation System in Highlander?
3 Answers
Highlander navigation removal method: Before removing the navigation system, use a trim removal tool to pry loose the air vents, remove the surrounding decorative panels, disconnect the internal connectors and the air conditioning regulator, then unscrew the mounting screws to detach the car's navigation unit. During removal, note that the navigation system contains numerous wiring connections; avoid excessive force to prevent cable damage. In terms of powertrain, the Highlander is equipped with a 3.5L V6 engine delivering up to 201kW output, paired with a stepped 5-speed automatic transmission with manual mode, ensuring smooth acceleration and excellent fuel efficiency. The Highlander's high-rigidity unibody chassis integrates well with its four-wheel-drive system, newly developed suspension, and 19-inch large-diameter wheels, providing outstanding handling, ride comfort, and off-road capability.
I've disassembled the Highlander navigation system twice myself. You'll need plastic pry tools and a Phillips screwdriver. First, disconnect the negative terminal of the battery for safety. Use the plastic pry tool to start from the gap in the center console panel, beginning with the silver trim strips on both sides of the AC control area. The clips are fragile, so be gentle. After removing the trim strips, you'll see four Phillips screws. Once these are removed, the entire panel can be taken off. Behind the navigation unit, there are power and data cable connectors—press the clips and pull them straight out. Be careful with the AC vent blades during disassembly; last time I was too forceful and nearly broke a blade. Finally, remove the four mounting screws of the navigation bracket to completely take it out. Avoid using metal tools throughout the process to prevent scratching the piano black panel.
Last time I helped my dad remove the navigation system from his 2018 Highlander, I found that special attention needed to be paid to the clip types. Using a plastic pry tool, I slowly peeled along the edges of the center console and stopped when I heard a click. After removing the hazard light button panel, the host fixing screws were hidden inside. It's best to take photos to remember the connector positions before unplugging the wiring harness—the gray one is the GPS antenna and is the easiest to plug in incorrectly. The whole process takes about 40 minutes. Those with strong hands-on skills are advised to wear anti-static gloves. Remember to turn off the dashcam power first. Last year, a friend didn't cut the power and burned a fuse, ending up with a tow truck to the shop and costing several hundred dollars.
