It is a method of implementing virtual streets that has a built-in map program and displays surrounding information such as maps, speed, direction, distance, gas stations, and restaurants necessary for driving.

However, since the embedded head-up display is integrated into the vehicle's dashboard, it has the disadvantage of having to select an expensive option when purchasing the vehicle, and also uses a built-in map program, so it does not provide information such as real-time traffic conditions or map changes. There is a disadvantage in that it does not reflect this, and in order to solve this problem, you have to subscribe to an integrated management service operated by the vehicle manufacturer and pay a flat fee.

In addition, in order to solve the shortcomings of the embedded head-up display, a stand-alone head-up display was released that can be placed on the dashboard of a factory vehicle. However, this stand-alone head-up display uses a map program built into the device. Accordingly, not only was the map data unreliable, but above all, it was unable to provide real-time traffic conditions or information, which led to consumer dissatisfaction with the product.
