I just bought the latest Navigation DVD upgrade (November 2006) “PT219-GEN-04” “DATA Ver. 06.1” from Lexus, and now I can no longer access the hidden Service Menu like I could in the previous version.
On my previous NAV DVD, I accessed the Service Menu by going to the “Sound Menu”, then:
Press top left, bottom left, top left, bottom left…then the Service Menu popped up.
Has anyone figured out how to access the “Service Menu” on the newest NAV DVD’s?
If so, please share it here.
