Yomikoo USB AUX Adapter: Enhance Mazda Car Audio with CD Changer Compatibility Review

Worked on my 2004 Mazda 6 with Bose audio system. If you know what you're doing, it takes about 30 minutes to install. there is a slight hum when you bang the cd, but when you turn the music up it's barely audible

If you have a new phone without a headphone jack, skipping a track with the radio or steering wheel will not work. You must use your phone 100%. Also, since you're using it without a charging port as there's no headphone jack, you can't charge your phone at the same time when you need a wireless charger.

Not too difficult to install. I watched a YouTube video on how to disassemble the order. It took me about an hour to take it apart and put it back together. Worked as soon as I connected it. I haven't tried USB, I just (and probably only) use an extra cable.

Easy to install, easy to use. The only problem is that when playing music from USB, even though it looks like you have 99 songs in each of the six folders, the playlist started repeating a song in about 50 places. No big deal. Much more crystal songs than a Bluetooth receiver that transmits FM signals.

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.

Easy to install, however the Mazda CX-7 is not designed for extra dash space so the wire protrudes from the dash for throwing. Also, the aux cable works great when plugged directly into my phone or other music source, but the card reader is a bit confusing. I used a 16GB SD card, but since the CD player's EX function only reads up to 6 CDs, it only reads the first 6 folders on the SD card.

A little note. I see the details saying this doesn't work with 2003-2004 series Miata Bose head units. Not true. It works. You press the "CD" key and it switches to it. The downside is that you can't play CDs while it's plugged in. But there doesn't seem to be many casualties. Who wants to keep CDs in the car? So yes, if you have a 2003-2004 Miata LS or Mazdaspeed with a 4H64 head unit and want to add aux (and therefore a Bluetooth adapter) to your Miata with a Bose head unit, this is the way…

The instructions say that for some cars you need to create six folders where you can add up to 100 songs. This mimics a CD changer working with the 'brains' of the stock head unit. It continues the song/track perfectly except in very cold weather below 5 degrees, so it's perfect for audio book/podcast use. In addition, if you copy your files using a Mac, you must enable hidden files (Google) and remove all folders created by the file system and other junk, otherwise this device will start…
