Don't know where my passkey #is.

Reset all bluetooth options, and enter new password when connecting to other device.

Once you make your phone discoverable, then put the headset into pairing mode by pressing the call control button until it flashes red and blue. The passkey is " 0000 " (four zeros). Here is a link for the pairing instructions:

Plantronics Explorer Pairing Instructions

Good luck from Headsets Direct!

When you are pairing any two 'smart' bluetooth enabled devices, like phones and computers, i.e. devices which act as bluetooth hosts, in the device where you are starting the pairing procedure, you can specify any digit sequence you can think of, provided that in the the other device, the one which will receive the pairing request, you specify that same passkey, because you will notice a request for that on the screen. Of course you can specify the passkey which is widely hardcoded in 'dumb' devices, like headsets, i.e. '0000' (four zeros, without the quotes). You don't need to worry whether the passkey looks too simple or not, because the devices will be paired to each other just once, under a process which is strictly controlled by you, and all subsequent connections between those devices will be encrypted.
Hope it works for you. Anyway, since english is not my natural language, please, let me know if I have misunterstood you. I'll do my best to try to help you out.

When you are pairing any two 'smart' devices, such as phones, computers, and such, i.e. devices which act as bluetooth 'hosts', in the device which you will use to start the pairing process, you can choose any digit sequence you can think of (e.g. you can specify the most common passkey used by 'dumb' devices, i.e. 0000 (four zeros)), provided that in the device which is receiving the pairing request, i.e. the other 'smart' device of yours, you specify that same passkey. You don't need to worry if the passkey you choose is too simple (like the one I've suggested above), because, once the devices are paired to each other, all subsequent connections between them will be encrypted.
I apologize if I havn't made myself much clear here, since english is not my natural english.
Anyway, please, let me know if I can help you out any further.

It should be in your Tomtom documentation. Usually default keys are 0000. You might also try 1234.

the pass key is like a password which is used to remember your phone once you connect it to the laptop. enter the passkey as you wish like your date of birth and enter the same in your phone also when you try to connect it to the computer.(after you give the passkey in the laptop, search for the phone and when it attemts to connect it will ask the passkey in your phone)

your default bluetooth passkey is 12345 if the passkey is not changed.
thanks

how do i find out my passkey for my samsung R210 Spex

As long as you enter the same code on both devices it pairs fine. I use 0000 on my mobile and the same on my laptop. There is no specific code.

Now, can you tell me where to get software for mine, please?

passkeys should be entered for both devices.
like when you are trying to paired your phone with you friend's
it would then asked to type in a passkey, you can type in any passkey you like but it should be same combination with your friend's. (so you can use 1234 punch in on yours and your friends need to use 1234 code punch in his phone, so both bluetooth device will be paired successfully).
