How would I go about getting my 2008 G37 coupe Bluetooth music without putting an entire new head unit in? I would even be fine with an aux port but all I have is the RCA cables to watch movies and stuff.

 

Lol, nice username.
I’ve been thinking the same thing, or I’d even be happy being able to play music from a stick but I don’t think we can

 

bluetooth dongle to iPhone 30-pin connector, and get a 30-pin to RCA and USB breakout cable. Look on Amazon for those search terms - there's tons of choices. Make sure you get AD2P 2.2 or higher.

 

Grom Vline did it for me. Not exactly cheap but if you want Bluetooth audio and like Carplay its worth it.

 

I haven't seen a full on Android Auto or Apple CarPlay solution but if it's just playing music over bluetooth you're looking for you can use a FM to Bluetooth transmitter. Sound quality is mediocre but could work

 

My 2011 had bluetooth as part of the head unit but on another car it doesn't but it has aux so I use a aux to bluetooth transmitter and it works well. Only thing is I have to turn on the dongle each time which is a bit annoying

 

This subject has been beaten to death in the forums already. There's good info in every post, just have to do some searching

 

$679.95 for 2GB RAM, and Android 8.1 sounds wrong.
