Really like this product, i use it mainly for sd card and get great sound through my car speakers. It also plays great from bluetooth on my phone. Had no problem installing it. Very easy to use. And it recharges my phone rapidly!
Only downsides are that it says in the instructions not to keep plugged in or it will drain the car battery. So u have to take it out and put it back in all the time.
U can select different folders on the sd card and it remebers where u left off. Display shows song title and band name.
