Review on Yomikoo USB AUX Adapter: Enhance Mazda Car Audio with CD Changer Compatibility by Prem Reyel

Very easy install. plug and play Our 2007 Mazda 6 has a 6-disc changer and I didn't have to unplug it; There was an extra plug on the back of the radio. The only thing that bothers me is that the USB control doesn't work with my Android. But the aux works great. There is a helpful video on YouTube to help with the installation if needed.
