Product Size
Size: 197.1mm196.8mm103.6mm (including bracket); Weight: 1236 ± 50g

Installation Requirements

• Keep the BT/WIFI antenna side at least 50 mm away from the metal parts of the body.
• Keep an operating space of at least 50 mm on the connector side to facilitate the bending of the wire harness.
• Keep at least 35 mm of natural convection space on both sides of the host to ensure enough space for heat dissipation. If the requirements cannot be met, be sure to use a convection vent.
• To ensure the effect of the cooling fins, make sure that the intersecting angle between the Z’ axis of the host and the Z axis of the car remains square, no more than ±90°.
• It is recommended to keep the host away from the air conditioning duct, as the size of the cooling hole is 2.6mm and has three side openings. There is no way to guarantee it will not be damaged by water.
• This device should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body.
