I've bought this adapter to retain the factyory USB when I've installed an aftermarket radio in my 2013 Ford F150. If you want to see my setup this is the video of my installation. https://youtu.be/JDzyyfe5g_c
Sorry for the trouble you had with the adapter and it not working for you. I will have our Product Management Team look into this and test out the product for any issues. It's possible you may have received a faulty item and I can issue an RMA for a replacement if you like. I would just need your order number to get the process started. Or if you would simply like a refund I can issue that for you. Again my apologies for any inconvenience this may have caused.

Saved us 10x the price
We recovered a set of Chill Pill speakers when one of our kids went to college. While they were unwanted by him, I coveted them so I could listen to Pandora over my cell phone while having my morning coffee only problem was I couldn't recharge the buggers without the adapter. Thanks to Monoprice and this perfectly functioning adapter, I've got NPR with my Italian roast and all is well.
I'm on the road about 80% of the time. Packing ligher and smaller is something I'm always interested in and these help immensely with this. Prevents me from having to carry around a wad of wires that I have to untangle when I get to a customer site or want to work in an airport.
I also get hassled a lot less by TSA as four of these look a lot less suspicious than a big old tangle of wires.
PROS: Super compact, super inexpensive, and hey, its a cable. It works. What else is there to ask for?
They're so cheap and so awesome I buy them a dozen at a time and give them to friends who see mine and inevtiably want one for themselves.
