How to adjust factory audio setting without SCAN button

[J.W]

I just installed TOY6VL2 to my 2011 Highlander Limited (Nav + JBL)
Everything works, however I can no longer adjust audio settings (treble/bass/etc).

- If I select Audio Setting from factory menu it would just switch to VLine interface
- The install manual says press SCAN button 3 times but I cannot find the SCAN button from my OEM dash

Any thoughts?

Here is a video showing how to add the "Factory UI" shortcut to the VLine which will allow you to access the OEM sound settings:
