I have bought this receiver in order my helmet speaker; redirect = true & ref_ = oh_aui_detailpage_o04_s00 operate. Wired the sound of my Huawei G750 was far too low and distorted.
The Bluetooth receiver is really tiny, so I just may get stuck in a recess of padding it with my helmet yet. The speakers I have soldered directly to the headphone socket in order to save the large end. The headset and the Bluetooth adapter are a perfect team. Now I can go great with navigation :)
Addendum:
Two Star deduction for a problem with the Navi announcements. The first 1-2 words each announcement are unfortunately swallowed. From "Turn left into ..." will "turn into ..." Not very helpful. Apparently, the receiver switches (from the power-saving mode?) Too late. My Bluetooth car radio does not show this effect.
I can manage myself "In 300 meters, turn left into ..." with the announcements. Not pretty, but goes.
