Thank you for viewing! This is a Tesla navigation system specifically for the first-generation GS. The large screen is very easy to see, and the larger navigation system significantly updates the interior's look! Bluetooth is now available! Also, by tethering with your smartphone, you can use YouTube, Netflix, and more! Apps like Netflix can be downloaded from the Play Store. Each unit has been tested for power, so the box has been opened once. Regarding installation, it's designed specifically for the vehicle model and is a simple plug-and-play design. However, if you lack installation knowledge or confidence, please have a professional install it. For compatibility, please compare the connector photos with your actual vehicle. We accept returns if there is a lighting malfunction after installation, but we do not accept returns for issues such as inability to install or incompatibility. Please understand this. Also, there have been complaints that the shape of the bracket on the back of the product is slightly different, but there are no issues with installation, so please be aware of this. Many other Tesla navigation systems are available, but they are geared towards those with installation knowledge, so the price is also lower. Please understand this before purchasing. The product is new and in stock. We will ship it on the same day or the next day. Please feel free to comment if you have any questions.
