The present invention relates to a device to measure an angle to install a product for a vehicle, capable of measuring an angle to install a product in a vehicle such as a navigator which affects a direction. According to the present invention, the device includes: an input part receiving settings of an installation angle measurement mode of the product installed in the vehicle; a rotation detecting sensor measuring a first rotation value depending on rotation when the vehicle rotates left or right on a preset horizontal land in the installation angle measurement mode of the product; a GNSS module measuring a second rotation value depending on the rotation on the land by using a received GNSS satellite signal; a calculating part calculating a difference between the first and second rotation values; and a control part searching a pre-stored matching table for an installation angle for the product, corresponding to the difference. According to the present invention, the installation angle for the product in the vehicle is able to be accurately measured and a rotation value error is able to be corrected depending on the installation angle. |
