A2DP Question for the Techies! :)

I have a company car that has built in Bluetooth, but ONLY for a phone connection. Apparently, the car does not support A2DP for music, etc. Phone calls route to the car radio speakers perfectly. Even Skype calls will automatically (after pairing) route through the speakers. However, podcasts, music, youtube, etc. will NOT play through the speakers. Since there is obviously a "path" from the phone to the car speakers via bluetooth (at least for phone calls and things that "look like" phone calls [Skype, etc.], is there a way to "trick" the phone and/or reroute other audio to the speakers via bluetooth (i.e. make the phone "think" the sound is a phone call and route it as such)?
P.S I am NOT rooted.

Any ideas greatly appreciated.
