Question: Can this device be used for in-car calls using the phone's microphone?
Document: Excellent product!! Comes with everything you need to used it. Did the NFC pairing once and my phone connects automatically to this  bluetooth device flawlessly every time I start my car. I have a Nexus 5 it's able to connect to my Subaru's hands free and this audio reciever simultaneously. When phone calls come in while music is playing the music pauses and the call comes through. Also when i use navigation from my phone it pauses the music, gives me the verbal directions and then resumes the music.
I bought this for my car to use it for music purposes. Please note that this device WILL NOT project your calls onto the speakers of your car. This is solely for audio purposes via Bluetooth.
I'm using this device in my car and it does exactly what I want it to. I'm very impressed.
I was looking for a device I could just plug into my car's audio-in jack and not worry about having all these wires to plug in just to play my phone's music.
I have used the HomeSpot for a limited time but I am very happy with the ease of installation and quality of sound. I have a 2011 Audi A4 that has Bluetooth for phone application but not for streaming audio, which is pretty ridiculous, so I was looking for an inexpensive fix. I looked at a few less expensive options, but they did not offer auto-connect to the device, which I wanted, so I went with HomeSpot.
This device is exactly what I was looking for. My 2000 F350 has an amazing audio system, installed in 2001. No USB in, no Bluetooth, but DVD, Screens, and a 5.1 Dolby receiver. I needed to get Podcasts and other audio content onto it easily. This device works great and is smart enough with an iPhone 5S not to transfer calls or Siri audio input through the BT device - just plain audio.
My vehicle has Bluetooth connection for voice only. I purchased this to use for streaming audio. My phone connects to the vehicle BT normally for calls, text, and navigation. The phone also connects to the HomeSpot for audio streaming. I've only had the device for a week so far, but it works great. It paired easily via NFC and the volume is good (another BT streaming device I had tried had terribly low volume). The Homespot unit turns on with vehicle power and automatically connects with my phone.
The DeviceIt does exactly what it says it will do, but it also came with one surprise for me. When I tapped my phone to the device, not only did it automatically connect with bluetooth, it also automatically launched Google Music (or whatever the latest music player you were using) and started playing. I can tap, and then start driving without anymore thought to it. No more fiddling with bluetooth, plugging in cords, or launching apps.
This works well and sound quality seems really good. NFC works as expected. The only problem is that if your using in your car it does not auto connect. So, you have to either open up the option in your phone to connect or use the NFC feature. Using the NFC feature is no problem but if you keep it in your center console as I do then it is kind of a pain.
Really nice to be able to hook up cell phone to the car via bluetooth but the sound quality isn't quite where I had hoped it would be. To be honest, I'm not 100% sure that the issue isn't with my phones a2dp driver or the phone not sending a high enough bit rate, but it does seem to be clearer especially in the bass when using a cable.
Answer: Hey A. H. Macias, Unfortunatly it can't I actually Baught it for that reason so I can listen to phone calls through mystereo but it switchs back to the handset or bluetooth talk device for phone calls.
