Bilan more than mixed - disappointed

The search for available FM band is as tedious and more unstable. We must repeat a full tour of the band to return to the first frequency. The device does not detect free frequency. A galley when you need to change course in frequency if unfortunately you were about 88.7 and 88.5 must be on board !!!. On the other hand, the FM audio transmission quality is average and regarding me need to increase the volume of my Philips car radio of about 50% .The level of its Bluetooth is also very "limit". Seller's return policy requires me to keep this product but I highly recommend. Better to put 5 or 10 more go see our Bluetooth car radio.
