This small Bluetooth receiver unpretentious done its job perfectly in my car (BMW 1 Series F20), which has in the armrest of a powered USB port and an AUX suite. The first recognition by the phone is effortless and the following connections are automatic when the car is opened. The receiver is automatically turned off also closing. Sound quality rendering is correct: we still feel the effects of high compression, but I think the record could be improved by using an AUX cable larger section and better. The product is, in any case, every penny. Note also the absence of micro-cuts in continuous listening.
In short, a product that I highly recommend for those with a USB port and AUX beside (careful, the delivered cables are short) and want to avoid unsightly son running in the car. For information, Amazon.de website packed with product assessments (they have convinced me to take the plunge in the absence of evaluation on the French site).
Information also important: the receiver supports bluetooth media part (not calls); in my case this is exactly my need, calls are already managed by the Bluetooth car.
As for the processing of the order, nothing to say, very fast shipment and good packaging.
