I have a 2008 Mazda 6i Sport and I'd like to install some sort of adapter or transmitter into it instead of having to use an FM transmitter which constantly and irregularly interrupts my media with interference. I know it's possible because my audio board even has a "media" button which I assume to be for that purpose. My brother and I disassembled the audio board and found an available audio input slot. After doing a little bit of research, my only guaranteed solution is buying the "Isimple", an apple product which is significantly overpriced for the purpose it serves. Also, many distributors like Best Buy, install it for you (which I don't need) to add on to the bill. Does anyone have a more affordable solution or an idea of where I can start?
