Need help getting bluetooth to work

[CaliforniaPlaya]

Been having weird issues with bt on the Evo since I got it. When pairing with a headunit, sometimes the headunit finds the Evo, but they wont pair. Once paired, a lot of times it won't connect. Once it does connect, bt audio cuts in and out and phone has a lot of static. I've tried unpairing and repairing. Using with different devices. Pairing from the Evo as well as from the bt device. Turning off other radios and wiifi in case thats conflicting and no luck.
Im running 3.29.651.5.

Thanks!!!
