Thank you for viewing! This is an Android navigation system specifically for the 180 series Crown Zero Crown. The Android navigation system not only allows you to use Bluetooth music, but also allows you to watch videos from YouTube, Netflix, etc., by tethering with your smartphone. You can also use other apps by downloading them from the Play Store. Depending on how you use it, you can enjoy a convenient and comfortable drive! It also has CarPlay and Android Auto, which is very convenient! Because it is designed specifically for the vehicle model, the frame fits perfectly, and the couplers are also included, making installation very easy, just by plugging in the couplers! The product has been tested for power-on confirmation. It is new and unused, but has been opened once for inspection. There are no instructions or videos for installation. Although it is a simple coupler-on design, if you are not confident in your installation knowledge, please have it installed by a specialist. The product is exclusively for the 18 Crown, but there may be cases where it is not compatible due to some options. If you are concerned, please compare the couplers in the photos with your actual vehicle! We accept returns if the product does not start, but we do not accept returns if it is not compatible, so please understand. We have stock, so we will ship it on the same day or the next day. Due to various circumstances, there may be delays, but we will contact you in that case.
