You recently bought a cassette-to-aux adaptor at a local drug store so you can play music from your MP3 player in your older car. However, when you insert the cassette into the older car's cassette player, the cassette player flips the cassette continuously. This guide will show you the steps to fixing the auto flip problem.

    • Place screws somewhere safe so you do not lose them.

  • Models, screw locations, and screw sizes may vary.

  • Slowly remove the cover of the cassette box.

    • Take a photo of the insides of the cassette box so it can guide when you are reassembling the cassette box.

  • Do not worry if you open the cassette box upside down (shown in 2nd photo) it is easy to correct; simply put the case back on, flip it over (shown in 3rd photo) and pull the new front side off (1st photo again).

  • Remove the auto flip mechanism located on the top corner.

    • Do not throw this away; you may have to reinstall it if you want to use a different cassette player.

  • Make sure all electrical circuitry and gears that were not removed are in their correct location.

  • Any other gears inside the cassette box, really aren't necessary. So feel free to remove them if the cassette is making too much noise (shown in 2nd photo).

Thank you so much! I bought an adapter, and thought I'd wasted the money. Thanks to your guide that wasn't the case, I can now enjoy my music in my car!

after I’ve removed all the gears it simply spits out the adapter. How do I fix this?

To reassemble your device, follow these instructions in reverse order, but do not replace the gears you removed.

It might have to do with the stereo in your car. When I made this guide, I was experiencing the problem in my 2000 Nissan Xterra, but my own guide didn’t help. Some stereos are just broken, like mine was. To be completely honest, I had no idea this guide would even work for people, like it is. Sorry it didn’t help fix your problem. I would suggest getting a new stereo installed in your car. If it’s an older car, you may be able to do it <$100 for a decent stereo. Cheers mate!

Worked for me. I used to buy these things new every couple of years. Glad I did not throw all the old ones out

Worked perfectly for me. I used to buy a new Phillips adapter every few years or have to return them.

Looks like a double post but still happy it worked!

Bought an older car just for Ubering. I needed to play music from my phone and when I bought a tape deck to mp3, it was flipping back and forth. I would have been s.o.l. if I didn't come across your page. Now I can Uber. Thank you for this post!

You should only remove the gear that has the rubber o-ring on it and the small gears that bridge that to the main sprockets. Keep the 2 sprockets and the gear between them. Most cassette players have a part that checks to see if the 2nd sprocket is turning. In a normal cassette the 2nd sprocket turns thanks to the 1st sprocket pulling on the tape which is wound around the 2nd. In these adapter that happens by the 1st sprocket turning the middle gear which turns the 2nd.

Thanks oldtech. I had removed all of the gears and my player would eject it out…by adding the top 3 back in it now works great.
