I was able to purchase the Logitech Bluetooth speaker adapter on Amazon through the goldbox deal; got it for $26 shipped! Tested it out, and it has great sound. I guess you get what you pay for...those chinese bluetooth streaming adapters are garbage.
I gutted the logitech and removed the 3 plugs off the motherboard (power, dual RCA, and 3.5mm). I then wired the 5v regulator from the BlueSaab board to the logitech for power, a ground wire, and then I spliced into the audio in wiring, keeping the BlueSaab board constantly connected to iPod input, but now there's a connector that attaches the logitech inputs. So basically I can disconnect the logitech board and it won't have any affect on the current capabilities/connections of the BlueSaab module.
This new board fits into the box I'm using; it's almost too perfect :)
The logitech has a button on it to initialize sync mode; So basically it works like this: if you have never connected a device to the logitech before, you HAVE to press this button to put it in sync mode. After you've synced a device to it, you never have to press that button again to connect the same device to it. If you want to connect a new device to the logitech, you'll have to pop the cover off and hit this sync button. I don't think I'll be syncing that many devices to the logitech, so I opted not to put a hole/button in the case housing just for this feature.
