Fcan't get it to work with my flashdrive. Very frustrating. I've about given up!t, pardon my typo: I have a Fiat 500, not a 500L.
What I need is a USB "passthrough" adaptor which sends power ONLY through one port, and data AND power through the other. I thought that was what I was getting through Amazon, but it turns out that it's technically a "hub," and thus doesn't do the job.
However, I went "down and dirty": I have a 32gb flash drive with my mp3 library plugged into the USB port in the glovebox, and the Miccus bluetooth receiver plugged into the "aux" jack. To power the Miccus, I have a cable running out of the glovebox, along the seam in the console, around to the 12v outlet, where I have a dual USB charger plugged in.
In truth, I'm down at the moment, because the Miccus gave up the ghost. However, a vast majority of the reviews of the Miccus were glowing; so, in the hope that I just got a bad one, I'm returning it to Amazon, and my replacement should arrive tomorrow.
I have most of the same music on my phone's SD card that is on the flash drive in the car; but what I really want is Pandora, Tune-In Radio, and a number of other audio apps to stream through the Fiat's stereo. It worked beautifully for a few days, and hopefully, will work again for a longer period
