SPYSEE 30-Pin Female to Micro USB 2.0 Male Dock Adapter | Compatible with Smartphones, Cars, Sound-Docks and More | 2018 Design, White (3 Pack)

My car stereo has an old school male 30 pin iPhone connector, which was of ZERO use to me since all my devices are micro USB. Rather than dig into the dash and try and find a way to change out the cable, I thought I should first try and adapter. This little adapter converts the male 30 pin iPhone connector into a micro B USB male connector. The quality of this part is a bit iffy, with the micro B connector coming out at bit of an angle on all three. But the 30 pin iPhone connector worked just fine. I wasn't brave enough to try and jam the somewhat angled micro B USB male connector directly into my phone, so I added a micro B USB male to USB A female adapter as well. Now I have a regular USB port, to which I connected my phone's regular cable and voila, it connected to my stereo and charges just fine. Then I removed the phone cable and plugged in a USB flash drive and the stereo read that and played music from it. So, I am a happy camper. I have a home stereo with an iPhone dock, so I might try one of the other 2 for that. But for the price, this was just what I needed. If you plan to plug and unplug this frequently, you probably should not buy it, since I am not sure it would survive more than a few cycles before breaking. But if, like me, you want to semi-permanently change a mostly useless male 30 pin iPhone connector into something useful, then this may be the part for you. For the price, its cheap to find out.

These are super cheaply made. The little tab bends once it hooks into my phone. Unusable.

Works, fits well.
