I installed the Navigation Bypass from Beat-Sonic (BS) on my 2009 LS 460. After the installation, my audio is dead. I have no display in the radio/CD unit, no sound, and the unit is totally non responsive. It does not turn on. The clock located above the nav unit is also blank.

The nav works, and the bypass works as expected. By pushing the button supplied by BS, all the features of the navigation system are active and accessible, while driving.

I rechecked all connections, checked all fuses (trunk, passenger side, driver side, and under hood), and couldn't find any fault.

Any ideas you may have will be greatly appreciated.

 

Keep us posted. I just had the NAV BYPASS/IPHONE INTERFACE done. Works great and the guys who did it gave me a life time guarantee.

 

Here's the last guy who had your problem.....

The small connector in the wrong place near the top of the unit made mine act like yours.
