Positives: - very small and compact, connections with iPhone 6 (in my case) without problems and also fully automatic, through the thin connecting cable it is practically easy to obstruct or to hide and thanks to USB and AUX I could play in my BMW E91 block ... The power supply is via USB (ignition), on the device itself, I can control my iPod via Bluetooth or Siri ... Since my iPhone on the center console hangs it's like a high quality speakerphone !!! There is also an indicator light ... The adhesive (Velcro) pad is quasi attach at any point ...
Negative: Nothing but the sound output only works via AUX can just hear no radio or ever have to stop to switch to AUX !!! But since this is not on the device, there are still 5 star !!!
In my case I have only the USB adapter to a shorter swapped because otherwise the plug are bent from the console!
For the price highly recommended !!!
