Bluetooth connectivity with selectable profiles

This may not be a big deal for most, but it really pisses me of when I connect my Windows Phone to my car using Bluetooth, it automatically starts streaming music from the cloud and I am on a premium data plan! I wish there was an option in WP so that I could specify what profiles to use when connecting to my car. I usually end up accessing the paired devices on my car and disconnect WP for music and just leave it for phone calls, and I have to do this every time I connect. However, if WP had an option so that I could select the profiles to use when connecting to my car, it would be so easier.
