Willnot pair w/ phone

Turn your headset off. Then, press and hold the answer/end button until the indicator light is solid lit in blue. It is in paring mode. Now, make your phone's bluetooth application search for new devices. After a while, the BT-350 should appear on-screen. Select it and command the application to proceed. If a pairing code (or PIN, or passkey) is requested, enter '0000' (four zeros). If the pairing proces is successful, the headset should enter stand-by mode. The pairing process is timed.If you fail to complete it, you'll have to start it over, from the phone turned off phase. Once paired, whenever both your headset and your phone's bluetooth radios are turned on, they should connect to each other automatically. Otherwise

Looks like your saying you've updated your n?vi 660 to software(firmware) version 2.0, if so you're moving in the right direction. Unfortunately the n?vi 660 does support the Treo 700P but only seems to support the 'Hands-free' BlueTooth profile and this is often problematical as is the 'headset' profile with some device combinations, that's precisely why many phones and devices now support both profiles. Check the pairing information to see if you're using 'headset' or 'Hands-free', whatever you're using delete the pairing on both devices and see if they will let you pair in the other profile. Your Treo 700P is made by PalmOne (www.palm.com) so you may want to check for software updates from them. This kind of problem is down to the lack of a solid standard for BlueTooth communications and you will often find that settings that work for one combination of devices are unstable with another. Post back if this doesn't help or if you need us to clarify anything.

The Motorola H700 has Bluetooth v1.2 which is backward compatible with v1.1. The headset works with both Hands-free and Headset profiles and is easy to pair with devices running various operating systems and software. We tested the headset with the Motorola SLVR, Palm Treo 650, the Nokia 9500, the Cingular 8125 and the Cingular 2125, and the headset paired with all devices with ease. To pair the Motorola, turn off the headset first then hold the Call button until the LED ring turns purple, quickly open the boom so that the LED stays solid purple, the headset is now in pairing mode. Use your mobile phone to discover and pair with the headset using “0000” as the default pass code. Call handling between the phone and the headset transferred smoothly and the headset will play notification or a ring tone when a call comes in. When working with the Treo 650, the H700 has an uncomfortably long delay in notifying an incoming call. It starts to ring after the Treo 650 has already ringed 2-3 times. The connection between the phone and the headset is solid. When we paired the Treo 650 to both the Motorola H700 and the Parrot 322 car kit, we can pick up calls on either one and the Motorola H700 worked reliably in this set up.

With the headset power off, press and hold
the Call button for 6 to 10 seconds until the
blue indicator light turns on and remains
steadily lit. (The light will flash while you
hold the Call button.)

If the indicator light is flashing or does not
remain steadily lit, turn off the headset and
repeat step 1.

Before you can use your headset, you must
pair (link) it with your phone.

Hi,
Here is a link to the plantronics online pairing guide and here is the link to download the m2500 user guide. Good luck!

there are known compatability issues with palm treo and blackberry phones when trying to use this type of headset .

I recomend a Plantronics brand headset with your phone.

Try using the following code: 0000 on the Palm Treo and your car's device. It worked for my BMW 328i
