Hoping this side of the forums can help me. Has anyone run into this. I have 05 RX330 no nav and no ml. I wired up the using TYTO-01. When I put the car to Acc I have sound. But when i turn it in the on or start the vehicle. I loose all sound. my first suspicious was no power to amp. To test this theory, I put the blue/white wire to the red acc. So this way when the car is in either acc or on. It would have power. I now have sound now. To reset. I then turn off the car and go into acc, I have sound. Crank and turn on the car. I loose sound. I check the blue/white white wire on the TYTO-01 and I have 14 v. If I remove that wire and reconnect it. I have sound.

Anyone have an idea of what is going on.

 

So i am thinking something is wrong with the head unit.

although, i did discover Axxess directions is incomplete/wrong.
