We might need to hard reset the phone. Follow all the steps mentioned in the website below:

can anyone tell me if my motorola phone can us a platronics bluetooth

Is your Palm Centro device locked up and frozen. You might want to try a hard reset. Here’s how.

1. Remove the battery from the rear of the unit.

2. Hold down the power button while reinserting the battery.

3. When the second Palm logo appears, release the power button.

4. Press the Up button to complete the hard reset and erase all data on the Centro.

Passcode is "0000"

Download the free app..."minitones"

I cannot say I have the answer to this, but I am using a Jabra JX10 and it is working well. I previously had a Nokia 6256i, which I loved, but wouldn't work with the bluetooth at all. If you have not tried a Jabra, I would recommend it. Also, if you haven;t tried for a replacement phone, consider the possibility it might be the phone itself.

How do I recover my old passwoed?

Email Restarts phone.
Sprint said make a new user because of 3rd party software but won't help otherwise.
Bluetooth won't work with my Pioneer DVD in dash Car receiver either.
Works with my Jabra headset though.
What gives? Any software I can download to fix?
Thanks

typical pairing code for PLT Voyager 510 is 0000
