This is one replacement navigation circuit board for your Lexus 2004-2006 LS430 navigation unit. You need this circuit board if current system displays, “check system”, “external system not connected”, or if screen is slow to respond to touch. Be sure to check your trunk mounted navigation drive and wiring if you are only having issues with the map or navigation system. The trunk unit will also display external system not connected if it went bad.
OEM part number 86114-60020.
If you are looking for the full display screen assembly (touch and screen) we carry the full assembly.
If you are ONLY experiencing touchscreen issues, we carry the digitizer panel separately that you can install onto your original display screen.
We do not offer any additional technical support for this DIY part.
If you are not confident in your abilities to install this, please contact us about sending your unit in for repair.
