Aftermarket Nav In Non-nav 05 Es330

[L1B3R7Y]

I ordered the ML center dash radio faceplate, brackets, screw and bolts.

A local stereo installer mounted my Avic-Z2 in the new bezel, installed a steering wheel interface so that I could continue to use the steering wheel controls and used the Metra 70-8113 amp/radio harness.

The problem: No audio. The steering controls work. Volume level changes on the Avic, radio works, Nav works, everything works, EXCEPT SOUND.

I found this thread while searching:

I know this is not the same model Lexus as mine and there's no resolution posted anyway.

Has anyone done this successfully?

Please help!

Thank you,

Scott
