Review on 🔌 Yomikoo Auxillary Adapter Y Cable Radio Wiring Harness for USB Adapter CD Changer (6+6) Pin - Compatible with 2003-2014 Toyota Camry, Corolla, Highlander, RAV4, Yaris by Curtis Nice

No big deal. My review is dedicated to Yomikoo Car USB MP3 Interface Adapter 3.5mm Car Adapter for Toyota 2x6P Radio. I use it with the iPhone 4s. I connect the iPhone computer cable to the USB cable of this product. All that happens through the USB port is charging, and it's not that fast. I also have to plug in the 3.5mm plug to hear sound. The audio output from the radio is very quiet and I have to turn the volume up - about twice as high as any other source. The 3.5mm plug is also too large in diameter to fully fit the phone jack due to my protective case. I had to take a knife to make a bigger hole. I don't have this problem with any of my regular headphones or headsets. Radio and steering wheel controls do not affect iPhone or music playback in any way - it was promised but doesn't work as advertised. I still have to test the USB interface with music on a USB stick. In general a bit disappointed. I would not buy this item again. ------ Update ----- Now I have tried the USB interface part of this device. He doesn't see my flash drive at all. So I'm sending it back and will look for another unit that works perfectly. I'm also downgrading my rating from 3 stars to 2 stars and my description from partially functional to minimally functional.
