Hey, got a tricky question here that I am unable to find an answer to..
I recently bought a new car, and I´m thinking about fitting it with an android tablet for gps purposes etc.
My idea is to buy a new tablet (probably Nexus 7 or Samsung Galaxy Tab 2), mount it to my car dashboard (got an idea to make it permanent and good-looking), and run an aux 3.5 mm sound cable from the tablet to my car stereo.
By doing it this way I can use the tablet to play music and have gps voice in my in-car-stereo, but still keep the parking sensors chime and other warning sounds.
My only problem is: How do I play music on the tablet?
I first thought about using an USB OTG cable, but the problem there is that I then can´t charge the tablet, or the phone, while connected.
So, I started thinking about bluetooth.
My question is: Can I, through the use of bluetooth, stream music from my android phone (not transfer files), to a tablet, so that it plays the music from the 3.5mm audio output?
OR, another idea: Can I connect the phone, with USB Mass Storage on the phone, to a tablet and play music, WHILE, after having cut the USB cable, providing BOTH the phone AND the tablet with power?
This would probably be done by cutting the cable, and running two 12v-cables from the car to the cut cable, one plugging into the cable going to the tablet, and the other to the cable in the phone direction.
Are my ideas just utter stupid, or perhaps doable?
All help, tips and ideas are greatly appreciated.
