This is the adapter I purchased. Better price, only $8
Been using this setup for a while in car and it works well. One thing to note: tablet talk will mute audio for most apps. I use a device (JL CL-SES) to handle audio inputs/switching so I've avoided the problem. You may need to manually pause some audio apps. I use this BT receiver http://www.amazon.com/gp/product/B00NP9SJ56?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00
The other Main issue with this is the answering calls bug in tablet talk. You still need to answer them from the phone. It's been acknowledged by the developers for almost a year with no update :(
I have brightech Bluetooth multi-media device and it's connected to my car audio in Port,with both the tablet and phone connect simultaneously. It works great for making calls and picking up music from the tablet /usb/hard drive setup. It is also high quality BT Audio.http://www.amazon.com/Cyber-Monday-Deal-Brightech-Simultaneously/dp/B00NP9SJ56
Only problem is I'm trying to get the tablet to react to ok Google or the Multifunction button. Every other app on the tablet reacts to the button except Google now. I some how have sound about recognizing the microphone from the tablet but I don't think it's using the BT mic. I'm going to try working with AutoVoice and Tasker and see if I can get something figured out. It only took me a few hours to get the 2 devices connected to the BT dongle.
