How to Correctly Configure Audio for CarPlay *Must Watch*Updated 4 days ago

This Article Will Tell You How to Correctly Configure Your Audio

Read this article before using a Lexus Hamilton Conversion Kit

Here is a video that shows the steps we outline below:

With the Hamilton Conversion Kits, it is important that you no longer use your factory Lexus Bluetooth network. 

Your phone will stream audio through to the Hamilton Conversion Kit, and the Hamilton Conversion Kit will play audio via the AUX line (our plugs tapped into this harness behind your factory radio). 

It is important that you have your phone paired only to your new Hamilton network. 

To Pair CarPlay:

1) Power on your Lexus

2) Open your iPhone Settings > Bluetooth > Look for a new device similar to "Hamilton-1234"

3) Approve the following prompts on your phone: 1) Tap "accept" to the pairing code 2) Tap "allow" to favorites and contacts 3) When the prompt to connect CarPlay appears, tap "connect"

4) Wait for CarPlay to Automatically appear after about 30 seconds

*MOST IMPORTANT* To Set AUX Mode:

Note: If you have a 2012-2015 Lexus RX, 2016-2019 Lexus RX, Lexus IS/RC, Lexus NX, or Lexus CT, long-holding the "menu" button in front of your knob/mouse/touchpad for 3-seconds will switch between the Hamilton OS and your Original Lexus OS. On a 2009-12 Lexus RX you will long-hold the phone-hangup button on the steering wheel instead. 

On you factory system it is very important to play music from CarPlay to set your Audio Source to "AUX" mode. 

Erasing Factory Bluetooth Pair Records - Important to Prevent Factory BT From Fighting Hamilton Network

It is very important to erase your factory iPhone pair records from your factory Lexus and from your factory Lexus network from your iPhone also. 

Long hold the voice-speech button on your steering wheel for 3 seconds to switch between the Hamilton OS and your factory Lexus OS. 

To Delete Lexus Pair Records:

1. Go to your original Lexus OS Home Screen. Click "Setup" > "Bluetooth" or "Audio" > Click "Bluetooth Audio Settings" > Remove your device from your factory Bluetooth pair records. We also recommend you turn off factory Lexus Bluetooth power from this menu. On some Lexus vehicles after you delete all pair records, the Bluetooth power automatically turns to "Off." That is ideal. 

You do not want your factory Bluetooth network trying to connect to your iPhone anymore. 

To Delete Lexus Bluetooth Network from Your iPhone

1. On your iPhone open Settings > Bluetooth > Locate your factory Lexus bluetooth name (Usually named "CARMULTIMEDIA") > Click (i) > Scroll to the bottom > Select "Forget This Device"

You do not want your iPhone to try and pair to your factory Bluetooth network anymore. On your iPhone this frequently appears as "CARMULTIMEDIA." 

Pro-Tip for Auto Connection:

If you want your Hamilton Conversion Kit to automatically connect and open CarPlay when you get in the car, from the Settings App on the Hamilton Home Page Select "Phone Connection Settings" from the left-side menu > Then turn "Auto Connection" and "Remember Device" both to the "on position.
