IMPORTANT WARNING, READ IT BEFORE DOWNLOAD 1. the main scope of this app is to ROUTE MULTIMEDIA AUDIO FLOWS ON BLUETOOTH EARPHONES supporting only phone calls, or CAR STEREO SYSTEMS interfaceable to bluetooth exclusively in telephone mode. 2. user must be conscious that the BT channels reserved for phone calls are MONO and LOW QUALITY, so DO NOT COMPLAIN for sound quality! 3. this app is GOOD and FREE (GRATIS), we all benefit from the existence of well-made and free apps, they are rare, let's preserve them, otherwise tomorrow we could PAY for worse apps! I am not a "commercial company", I am alone, and I creat apps by "pure passion", they "survive" only for my passion, feeded by your 5 stars and rarely watching some ads! If you have problems, write me at the developer's address here reported!
APP DESCRIPTION
Its main scope is to route MULTIMEDIA audio flows on: 1. stereo car systems, which can be interfaced via bluetooth exclusively in telephone mode, or used as such 2. bluetooth earphones supporting only phone calls (not equipped with multimedia channels).
More specifically, this app lets you stream multimedia content (audio, music, etc.) to bluetooth devices that DO NOT support multimedia channels, but only "phone calls".
Usually such devices, such as stereo car systems or mono headphones, do not allow you to listen to audio streams and music with Bluetooth headphones. Instead, with this app, all this will become possible, specifically you can listen to voice messages from my FREE NOTIFICATION READER!
Common issues due to devices and Android limits: - the sound quality is not particularly good - not all smartphone models are compatible - there are some problems with Samsung Galaxy S2 and S3 (and not only) - sometimes the process may be interrupted by Android.
ENJOY IT!
Recent changes: Version 8 has many news, more automation, and best graphics. Major news: 1. a refined management of bluetooth connections, now perfectly integrated in the app 2. AUTOMATIC opening option of the call with relative choice of BT devices that will be able to enable the automatic call 3. a refined system to make advertising pleasant, which also includes a very nice little game 4. CHINESE 5. ARABIC 6. TURKISH

Works as advertised, no weird permissions. Convenient widget button. Is it possible to activate when there's audio only? I normally listen to the car radio and occasionally use GPS. Would be nice to the hear the step-by-step instructions over the car speakers. Some navigation app has "play as Bluetooth phone call" option, but not Waze.

The main reason I used this app was because I wanted to record with my Bluetooth headset, and it works just fine thanks

Not working on Huawei Nova3i with built-in FM Radio. It will just turn off the radio music, then it will send a low frequency sound in the Bluetooth headset. But no music can be heard.

Requires access to stuff it shouldn't have access to, plus it makes you watch 30 sec ads for anything.
