Yep, the next step.
Continuing the low cost theme, bought this adapter from Amazon.
Belkin F8Z492TTP Bluetooth Music Receiver
Good specs, good price, so I added it to my previous aux mod, allowing me to plug in any MP3 player or bluetooth attach any smart device.
Plays Pandora or MP3s straight off my phone without any wires. (Well OK, have to plug in the phone's power cable after a few hours of listening)
Installed a widget app on the phone that turns on the bluetooth and connects to the Belkin by pressing one icon.
Did have one issue where I have a dedicated power converter (hacked car USB power adapter) that made a static noise. Seems that these converters use a switch mode power converter chip that is great for charging but makes noise on the audio side. Tried several before I just gutted one and used a 7805 from R*Shack as a 5 volt supply. The Belkin only takes about 180mA, so with the voltage drop and current output it dissipates less than 2 watts, not much heat at all.
After everything I have about $30 in the mod, it is dead simple to use and sounds great to boot.
Much discussion about bluetooth compressing the audio, etc, etc. Well with the A2DP and EDR the bluetooth side isn't going to affect the music quality at all. Pandora (free version) at best is 192K and most compress MP3s to 256K or less, so unless you are listening to a CD/DVD you are losing some audio quality.
I am quite happy with the results, YMMV.
