I've had experience removing the Highlander's navigation system, which is part of the fun for DIY enthusiasts. Remember to first disconnect the negative terminal of the car battery—just loosen it with a wrench to ensure safety. Next, prepare a set of plastic pry tools; avoid using metal tools to prevent scratching the dashboard. Start by gently prying open the decorative cover from the top left corner of the instrument panel. There are many clips, so be careful not to break them. Carefully remove the air vent panel to expose the navigation unit, which has several cable connectors. Take photos to record the position of each wire, then unplug them in order to avoid damaging the cables. The unit might be secured with screws, so use a Phillips-head screwdriver to loosen and remove them. After removal, test all functions when reinstalling to ensure everything works properly. It's best to do this in a spacious area, and the process might take about an hour. Don’t forget to check video references for your specific model year.
