wm device center bluetooth sync

I am trying to get a WM5 device to sync with Vista via Bluethooth. I have tried a lot of different things without any luck and have yet to see any comments indicating that this is has been successful.
I have all the WM Device Center updates including the v2 update on 7/6. I am able to sync fine with USB. In addition, I am able to connect my device using Bluetooth (MS native BT stack). When I pair the devices, Windows recognizes 6 services on the device but does not have a driver for all of them. For the services that it does not have a driver for the wizard will prompt for to locate a driver for the "Bluetooth Peripheral Device" and I have to just cancel out. However, there is a driver for the serial port service and this should be all that is needed for the sync. I have a incoming BT COM port (com7) and even an outgoing BT COM port (com6) specific to my device.
So when I intiate a connection from the device, it is able connect to the PC and even initate a connection in WM Device Manger. However, WM device center will just show that is "Connecting..." for a couple minutes and then error out. It will never actually be connected.
Just looking for others to share experiences. Any hints would be much appreciated.
