Wireless and wired CarPlay and Android Auto. Preserve all Lexus factory functionality.
We are excited to introduce the 2013-2015 Lexus LS Hamilton Upgrade Kit for CarPlay and Android Auto. Our engineers have carefully designed this system from the ground up to integrate wireless and wired Apple CarPlay and Android Auto capabilities right into your factory LS display. The Hamilton Upgrade Kit allows you to retain all your original factory features, including your backup camera, factory microphone, and steering wheel controls. You also have the ability to hop back into your factory Lexus OS at any time.
Access your original Lexus Interface with ease.
If you wish to switch back to your original Lexus system, you may do so at any time by simply long-holding the menu button in front of your mouse. The Hamilton Upgrade Kit was designed to use your factory XM, FM, and AM radio, as well as your factory navigation system.
Please note the Hamilton Upgrade Kit only takes over the left portion of the screen. The right-side information panel cannot be overtaken by any aftermarket system due to Lexus original system constraints. See product photos for detail.

Frequently Asked Questions
Are there any important limitations to note?
The 2013-2015 Lexus LS factory screen is an original Lexus split screen. On this model vehicle (older than 2016), CarPlay will only occupy the larger left-hand portion of the screen. It will not be full screen.
Does the Hamilton Upgrade Kit support both wireless and wired CarPlay and Android Auto?
Yes, we support both wireless and wired CarPlay and Android Auto. You can access your original factory OS at any time by long-holding your voice speech/menu button (this button may vary model to model; please check your pairing and setup video on our manuals page).
What makes the Hamilton Upgrade Kits stand alone on the market?
We employ some of the finest engineers in the world in this aftermarket CarPlay/Android Auto space. We do our testing here in the USA. This means we leverage our partnerships to locate American vehicles and gather all of our data off American cars. This way, we can be certain we do not disrupt factory equipment.
For our electronics, we use gold-plated PCB technology and premium components throughout. We use high quality harnesses and connectors to minimize the risk of damaging your wiring during installation and to protect against wiring faults. Also, we use a top-of-the-line reputable chipset that is specifically tailored for automotive applications.
Can I use FM, XM, or AM radio while CarPlay/Android Auto is showing on the screen? Are all factory audio channels still available?
You can use your factory radio channels and have CarPlay/Android Auto showing on your screen with the Hamilton Upgrade Kits with one important limitation: Please note that the factory radio channels are sealed channels. This means Siri cannot talk through these channels.
When you are streaming audio via CarPlay (e.g. Spotify, Apple Music, Sirius App, etc.), your music and Siri/Navigation will come out of your vehicle speakers mixed together.
However, while using the sealed factory radio channels, you will only be able to hear radio audio. System audio (Siri, navigation sounds, phone calls) cannot be mixed into the factory radio channels.
Note: You will not be able to use the AUX port for any external media devices liked DACs or MP3 players. The Hamilton Upgrade Kit consumes this audio input for CarPlay/Android Auto.
Playing audio via the factory USB port is not supported while using CarPlay/Android Auto. If you prefer USB, please use wired CarPlay/Android Auto.
