Are you looking for the best dash cam for toyota corolla?

Toyota Corolla's built-in dash camera is a fantastic feature that enhances safety and provides an extra layer of security while driving. In this article we will show you dash cam installation toyota corolla, now let us walk you through the process of hard-wiring the built-in dash camera in your Toyota Corolla, ensuring a seamless and efficient experience.

Let us see the trim look like before the dashcam for toyota corolla install,there is no casing behind the rear-view mirror, so with this U shape hidden dashcam can blend in therer so well that you can actually forgot it's there.

First look at the A99 toyota corolla hatchback dash cam after install, it doesn’t have a screen and installation seamless.

Dashcam Install Materials Needed:
Before you start the hard-wiring process, gather the necessary materials:

Hard-wire kit: There is a hard-wire kit in the A99 hidden dashcam compatible with your Toyota Corolla's dash camera.

Trim removal tools: You may need these tools to access the necessary panels and hide the wiring neatly.It also contain in the dashcam's package of mercylion A99.

Multimeter: Useful for checking electrical connections and ensuring proper voltage.

Steps to install the front dash camera on Your Toyota Corolla

The picture below is a simple diagram of the instructions for the A99 main unit to help you understand the structure and installation method of the recorder more clearly.

Let's proceed with the actual installation. Ensure that your vehicle is turned off before attempting any installation.
Step 1: First, clean the position where the windshield is to be installed, and then open the protective film of 3M glue and stick it in an appropriate position.

The base plate here can be separated from the main unit. You can try removing the main unit when get the main unit in your hand, tearing off the protective film of the front camera lens, and then reinstalling the main unit to the base plate again.

Power Wire Connection:
Connect the power cable to the front cam, and connect the rear cam cable to the front cam at the same time.
Route the Wiring
Carefully route the wiring from the dash camera to the fuse box. Use trim removal tools to tuck the wiring into the interior panels, ensuring a clean and inconspicuous installation.

Locate the Fuse Box
Locate your Toyota Corolla's fuse box. Typically, you can find it beneath the dashboard. Once located, identify the constant power fuse slot and the ACC fuse slot. You can first use the vehicle's electrical diagram (vehicle manual or online resources) to know the power cables related to ACC, Constant, and Ignition Switched in the fuse box. This information is usually marked with corresponding symbols and colors in the electrical diagram.
Connect a multimeter:
Set the multimeter to DC Voltage mode and select the appropriate voltage range. Usually, the vehicle system operates at 12V and can choose a range of 20V DC.
Measuring constant current (constant power supply):

Connect the black probe to the negative electrode.

Use a red probe to touch different circuits of the vehicle, such as the location marked with constant current in the fuse box. When the current passes through a constant current, the multimeter displays the voltage(When the car is not started, there is always about 12.4V voltage).
Measuring constant current (constant power supply):
The voltage that ACC only has when the car is started is about 14.5V, and the voltage will automatically turn off immediately after the car is turned off.
Connect the dashcam hardwiring cable tape to the slot we identify.
Measurement position (ground wire):
Select the resistance measurement range and make sure to select the appropriate resistance measurement range before starting. Usually, select a smaller range to improve sensitivity. Before measuring the ground wire, ensure that the relevant circuit is closed to prevent current interference. Connect the black probe to the metal part of the vehicle, such as the metal frame of the vehicle body or the negative pole of the battery. This is the place commonly used as a ground wire on vehicles. Connect the red probe to the location you want to test, where you suspect it may be the ground wire. After connecting the probe, check the resistance value displayed on the multimeter. If the circuit is well connected, the resistance value will approach zero.
