Set up easy enough. But I find it a little temperamental.
If I am travelling long distances it obviously gets affected by other radio station in different areas. You can switch to the other frequency in the memory but its no guarantee that will work any better!

Hold it in your hand to get clearer reception! Not the safest thing to do while driving.
Make sure your phone is turned up to full volume!!!
At the end of the day it's a charger as well.
