How to Disassemble the Highlander Navigation System?
4 Answers
The method to disassemble the Highlander navigation system is as follows: Before removing the navigation, use a trim removal tool to pry loose the air vents, remove the surrounding decorative panels, disconnect the internal plugs and the air conditioning regulator, then unscrew the fixing screws. This will allow the car's navigation system to be removed. During the disassembly process, it's important to note that the navigation system contains numerous internal wires. Avoid applying excessive force to prevent damaging the wiring. The Highlander is a mid-size 5-door, 5-seat SUV with dimensions of 4890mm in length, 1925mm in width, and 1720mm in height, and a wheelbase of 2790mm. It is equipped with a 2.0T turbocharged engine, delivering a maximum power of 162 kW and a maximum torque of 350 Nm. The front suspension uses a MacPherson strut independent suspension, while the rear suspension employs an E-type multi-link independent suspension.
I once took apart the navigation system in my Highlander, it was quite fun. First, prepare the tools: plastic pry tools and a Phillips screwdriver. Don't forget to disconnect the negative terminal of the car battery first to prevent short-circuit risks. Then start from the center console, gently pry open the edges of the panel—some clips hold it in place, so don't use too much force to avoid scratching the interior. Once opened, you'll see the screws securing the navigation unit; loosen them and set them aside carefully. Next, unplug all the wiring connectors, and remember to take photos to note their original positions, otherwise, it's easy to mix them up when reassembling. The whole process tests your patience a bit. If it's your first time, it's best to have a friend help keep an eye out. It also makes installing a new navigation system or upgrading easier—I went through this to replace mine with a better screen. After finishing, remember to test all functions to ensure everything works properly.
From daily car repair experience, removing the Highlander's navigation system isn't difficult, but steps must be precise. First, disconnect the battery with a wrench to avoid accidental ignition. Don't pry the panel by hand - use plastic tools for gentle leverage to protect the paint. The head unit is usually secured with screws, locate and loosen them. Always unplug cable connectors slowly, never yank to avoid damaging terminals. If you're inexperienced, we recommend watching tutorial videos first. The process might trigger the alarm system, so have the reset code ready. With proper tools prepared, the job goes faster and saves repair costs for upgrading components.
I was quite nervous when I dismantled the Highlander navigation system myself. Starting with the basics, power disconnection is the top priority for safety. Panel removal is crucial, and gentle movements are necessary to prevent breakage. There aren't many screw positions; once loosened, the unit can be taken out. Pay close attention to the labeled positions of the cables. Incorrectly connecting the cables by mistake might cause system errors. It's advisable for non-professionals to avoid DIY attempts and seek repairs from authorized shops for better security. After all, the navigation system integrates safety functions, and damaging it would cost more to repair, which isn't worth it.
