So, I have just purchased the new Samsung r610 slider phone, and had the BTB-200 Bluetooth module already installed. I try to pair the two, and the phone detects the Pioneer unit...the Pioneer unit detects the phone. However, when I try to pair the two, the phone is perpetually in the "pairing" message screen. The Pioneer unit displays "connection error". Twice, I received a "connected" message on the headunit, but the phone still said "pairing". As soon as I slid the phone shut again, the connection was gone. The second time I got "connected" to appear, it lost connection in about twenty seconds. The phone never actually says "successful pairing". Not sure what to do here, people. I tried to get this to work for almost two hours. You'd think a new Samsung would be compatible with this module. Any help is appreciated! Thanks!

Okay, so I performed a little test. I took my friend's $0 Samsung phone out to my car and tried the Bluetooth functionality. Flawless. I must say it's gotta be my new phone then, right? That's the only thing it could be, right?

most likely, your new phone probably has bt 2.0 and the old phone 1.1 so thats where the issues probably arise.
