A local stereo shop installed my Avic-Z2 last night...almost.

Unit comes on, navigation works, steering wheel controls work, but no sound.

Installer used Metra harness 70-8113. It is not listed for my car, but seems to have all the right wires and the 20 pin connector is correct.

We can't tell whether the amp is powered on or whether the sound is muted.

Anyone done this install and been able to use the stock amp? I know I can bypass the amp and just grab the speaker wires coming out of the amp, but I would lose the factory sub. I was hoping to retain use of the factory amp for now.

Any one have any ideas?

Thanks,

Scott

Hi

I just wanted to ask you if you ever found a solution to your problem and how did you do it?

I have a 2002 es 300 and am installing the avic z2 and experiencing the same problem.

2005 Lexus ES330 - Avic-Z2 - factory amp - no sound

Thanks for the help and response

I never figured it out. Posted on the Lexus forums too with no response.

I ended up bypassing the factoring amp and installed a separate amp to power the sub. Not what I was hoping for, but...

Thanks for the reply

guess I would have to do the same

Hey 95ImpSS

Can you post a pic so I can see how yours look like in your car? How was the fit and finish of the deck in the car.

Please please
