Does anyone know how too access the service menu for the car?? There are many good tips on the older GS and other Lexus that allow you to turn off the overrides for the cellphone dialer when driving and improve the Bluetooth phone sounds a little bit.

 

Try holding DISP while turning on/off headlight for 3 times. It's work on Toyota. I'll try mine tomorrow.

 

Ok because I tried this method from someone else and it did not work after several attempts. Its pressing the menu button while turning lights off/on.

If anyone gets it to work, let me know.

 

Pressing MENU while cycle headlight on/off 3 - 4 times will grant you access to service menu with engine running.

Look like Head unit made by Pioneer, Power/AMP made by Becker/Harman, Touch screen/control/NAV/GPS by Denso. Not much info to change inside. May be there another service menu hidden like Infiniti have 2 service menu.

 

Hey thank you!! I got into the service menu and increased my receive volume to plus 1 to increase the sound quality of the phone bluetooth.

 

What other useful things can be done when in this menu?

 

You can look some specs, GPS info, error code, checking if a switch/button working.
