Have the Decrescent Bluetooth receiver BTR195 for a week in older BMW 3 Series in operation. There the auxiliary jack located in the center console. To connect an MP3 player or iPhone I have so far used a mini-jack cable that was inevitably crushed by the arm and therefore went already twice broken. This problem is a thing of the past since last week. The BTR195 settled completely take problems in operation, the pairing with the Iphone worked right away and the sound is absolutely convincing. The unit comes out with a mini switch on / off, while a voice says "Power On" or "Power Off". This allows you to have to look the BTR195 in the car while driving without on and off. Experience with the battery I have not because after approximately 8 hours operation, no need to reload. I can wholeheartedly recommend an all-round super device. Congratulations to the developers, better and cheaper, you can not do it !!
