need bluetooth dongle to connect laptop to car stereo?

[chase]

I'd like to tether my computer to my pioneer deh-80prs car stereo via bluetooth. My computer is an older hp pavilion g6 and does not have a bluetooth adapter that i know of. The 80-prs has bluetooth and i have connected many phones to it in the past. I tried purchasing a cheap (under $5) bluetooth dongle off ebay but the software that came along with it was terrible and i couldnt get anything to work. Where can i get the software to make this work? Or, alternatively get a completely different hardware/software setup? I'd like to connect just as easily with my computer as i do with my phone. I don't mind reading if you have some good educative links for me. Most useful answer gets 5 star and best answer.

Thanks for the help in advance!
