Frequently Asked Questions
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.
