In my car i have a 3.5mm jack that I want to connect to my iPhone 5. I currently am just running a standard 3.5mm cable from my phone to the port, but that audio volume isn't that great. So I thought a neat way would be to get a Bluetooth module with a 3.5mm input - like this one - http://goo.gl/brbcW - and use that.
But I'm not sure if that would connect via a line level output from the phone.
Is is possible to do line level out without needing an expensive lighting to 30 pin cable -> 30 pin to 3.5mm cable into the car port?
OR is it possible to just go lighting cable to this, right into the 3.5mm jack, would it carry audio??? http://goo.gl/NBPC5
