Simple and easy just kinda lost on what to get for streaming music to my "old" pioneer deck in my vehicle. I say old, but its about 4 years old and i might just replace it when money becomes more available. I'm trying to decide in the mean time best connection method is A2DP dongle/APT-X reciever or gold plated heavy duty 3.5 cord. I'm currently using GoneMad on my S4 and just want as best sound possible out of the whole setup. Thoughts anyone as to what is "better" to use? TIA
