Fabulous items in terms of connectivity, usability and transformed old music stereo in new one.also having charging facility with C type and 3.1 Amp.you can play your song by USB also.

Working fine. Initially I was in confusion that how it works without any connection with car's music system. After installing this I understood. Its sound quality is good enough, bluetooth ramge us also good. Calling function also working fine. This review is based on 4days of use.

I had ordered it as a cheaper alternative as the touch screen of my car got dysfunctional and was switching bluetooth automatically off and changing the tracks of its own (as the stereo is almost 11 years old) These are my observations : its an boon for those car stereo system which do not have a in-built bluetooth. The connectivity to the mobile via bluetooth is very fast, calling quality is descent as the in-built mic of the device is not giving HD quality output, there is some noise in the background but the receiver can listen and comprehend the conversation easily although it may not be HD quality as comes with the original bluetooth car stereo (sound not as clear as you get if you talk with the speakers of the phone). 2. Charging quality is good from 3.1 volt port, 3.Equalizer function is good. 4 The sound quality of the music system of your car will give a lower performance in terms of clarity and overall sound output, if you play new heavy bass music via this device. It probably bypass the dolby or other features of car stereo system while transferring the sound via this device. That's why 4 star (1 star deduction for average MIC and lowering the sound quality output). But i still say, that it can convert the non bluetooth car stereo in to the advanced system with USB music, bluetooth connection with the phone and hands free calling. If you need to hear new and heavy bass songs, connect 3.5 mm jack audio cable via aux of the car stereo, other wise all other songs sounds good.

The product for its price is very good, however you will be able to hear a bit of static in the higher volume stages. The quantity of your voice for the person on call with you will be less. You will be able to hear them clearly however the mic will not pick your audio clearly. All in all 6/10.

Functionality = 10/10 (for honda city ZX 2010 model). Fast charging is not available though. Also the power connection seems to fail when starting the car sometimes. might be the problem with car as well as it is too old. Bluetooth connection with phone = 10/10. It gets connected automatically if paired once before. Call quality is also good - depends on the kind of speaker system you have installed in your car. Mine was stock and it was still good. Controls seem a bit confusing at first, but will get used to it with gradual use.
