When i enter the passcode it tell me passcode mismatch

oh..............!! you can try 1111 on your pc first......then the cnnect your mobile to the pc and when they ask for the pass code in your mobile type the same (that is 1111)........this is my suggestion...you keep trying it.....thats what i did......if you are lucky you problem is solved.

The passcode is usually 0000 or 1234 by default.

i'm assuming your device is picking up the headset just not accepting the code.

has the device ever been linked to another before? Motorola headsets are/were known for only being able to sync to one item.

Bad News... you may have to Restore from iTunes. Here is some info from the users manual:
Passcode Lock By default, iPhone doesn’t require you to enter a passcode to unlock it. Set a passcode: Choose General > Passcode Lock and enter a 4-digit passcode, then enter the passcode again to verify it. iPhone then requires you to enter the passcode to unlock it or to display the passcode lock settings.
Turn passcode lock off: Choose General > Passcode Lock, enter your passcode, and tap Turn Passcode Off, then enter your passcode again. Change the passcode: Choose General > Passcode Lock, enter your passcode, and tap Change Passcode. Enter your passcode again, then enter and reenter your new passcode.
If you forget your passcode, you must restore the iPhone software. See “Updating and Restoring iPhone Software” on page 204.
Set how long before your passcode is required: Choose General > Passcode Lock and enter your passcode. Tap Require Passcode, then select how long iPhone can be idle before you need to enter a passcode to unlock it.

Are you entering the passcode on your phone or the other device. If it's your phone, make sure you use the PIN that you entered on the first device. When using headsets, the PIN should be written in the documentation somewhere. If you are trying to enter the PIN on another device when connecting to your phone, then make sure you enter in the same code into your phone, then into the other device. If your phone never asks for a PIN first, then check your Bluetooth or Connectivity settings and make sure you know and are using the same code as there. Hope this helps...

password are for security and privacy reasons..
missmatched password while pairing bluetooth devices means you have entered incorrect pass code.
usually the the device A you are searching with asked you to create a pass code when you are pairing device B. When connection is establishing, device B will ask you for the pass code you just created for pairing device A with device B. this pass code is different for each and everytime you connect to a device.

the traditional 0000 passcode did not work with my new SA505, being frustrated I decided to just start at one and put four 1111 in, and low and behold it worked. I now can pair it and it works great, Just a lucky guess but hey it worked.

It doesn't matter what the code is, as long as you enter the same number at both ends
