How would I use a RN-52 module to play music from my iPhone to my car

Hiya!

I just put in an order for an RN-52 module and I have an Arduino laying around. How would I go about setting up the module so that I can connect and play music from my phone and wire it into the aux( or some other function ) of my car radio? I'm not too sure if I would need an audio shield or anything else. Any help would be appreciated.

Thank you!

I don’t think an Arduino is needed at all, it will work stand alone.

Would I need to set up anything software-wise?

Yes you would need to put it in the right mode and you would need to pair it with your phone.

You are using an expensive two way audio board when all you need is a cheap one way board. No Arduinos need to be involved.

How should I go about doing this the cheap way?
I already own an Arduino, but I could save it for a later project.

Get a Bluetooth sound module from ebay, something like this:-

My car doesn't have an aux jack. I'll need to hijack one if the functions, probably CD as I don't use them.

Just get a 3.5mm audio jack socket and wire it into some input function of your car's audio system.

Wanna keep it wireless though.

It is wireless, do you not understand what I have said?

There is a wireless connection between your phone and the Bluetooth module. Then you wire from the Bluetooth module into you car’s audio system. I am assuming your car has not got a wireless input to it.

Ahhh, gotcha. That's correct, I do not have a wireless input.
