So I started brain storming an project idea but I have run into a snag. I want to replace my Trucks head unit with a Google Nexus 7. This on its own isnt to hard. I have the power suply licked and I have the perfect spot in my dash for the tablet (once I relocate the AC controls. I will run an exteral amplifier for the speakers but I really wanted to retain my Hands free phone calling abilities. To my suprise, there is not software that will allow the audio from a phone call to be redirrected to my tablet. I did find an app that will allow the tablet to be the caller ID device and allert you of the phone call. At this point, I think I would have to use a Parrot bluetooth, unit that will accept two devices at once ( one for media and phone for calls) as a "pre amp" to accomplish this goal. Any one that may have a better method, please let me know.
