Jailbreak broke my Bluetooth... I think.

OK, I have an iPhone 3GS, running 3.1.3, JB with Spirit. I bought a Kenwood KDC-BT742U deck for my truck. BEFORE the JB I could pair my iPhone to the Kenwood flawlessly. Since JBing though my iPhone says it's paired. If I make a call it will lower the music as usual and I even get the option on my iPhone to switch between Bluetooth, iPhone, or Speaker. But on my Kenwood I no longer get any sound and the indicator for Bluetooth no longer comes on. But it does seem to be paired properly. I eve tried resetting the stereo and iPhone. I made sure that I told my iPhone to "forget the device" and the same with the Kenwood. I then repaired and it does the same thing.

Please help a brother out. Thanks in advance for any and all help.
