Review on 12V Bluetooth Receiver Adaptor-Dongle for Car, Boat, and Spa Stereo Conversion by Flavio Iyer

I installed this in the rear aux to add Bluetooth to my old Kenwood kit in the truck. It is hardwired to both the aux-in and the vehicle's key-controlled battery. Great connectivity, great sound, upgraded audio system. I'm not an audiophile so the sound quality may not be as great as yours, but for me it's good for what I use it for. I'm tired of the 3.5mm cables constantly getting in the way, so now my music connects via BT and I no longer have those pesky cables.
