Pairing tomtom 630. it connects and works 1 time then tomtom complains about phone not responding. i did connect and after this i authorized it should work. tried with different nokia 5800 same problem. Also tried with an upgraded tomtom also same problem. tomtom connects well with different mobiles.

I detest cell phones, but here's how I got my wife's BB8100 and BB8800 to connect to my GO930:
1) Press the button with 7 dots in a circular pattern (Menu?);
2) Click "Options";
3) Click "Bluetooth";
4) Click "TomTom GO 930" (yours may differ);
5) Click "Full Menu";
6) Click "Options";
7) Change "Discoverable" to "Yes";
8) Press the button with the curved arrow (Return?);
9) Click "Save";
10) Click the curved-arrow button until the menus are gone.
The TomTom should now be able to connect to the BB.

Had to do something similar on the iPhone 4 before it could connect (haven't found a "Trust" option yet).

default password for pairing any phone with tomtom go 630 is 0000. some phones require you type the password and some do not.

When you are pairing your TOMTOM with a BlueTooth-enabled cellular phone, your TomTom will ask you to enter "0000" when the phone asks for a pin. In order not to have to enter the pass code every time you want to connect to the phone, declare the TomTom as a trusted device.
When you are pairing the two make sure that the phone is "visible for xxxx minutes" or "always visible".

PAIRING A PHONE WITH YOUR 2009 Silverado

Before you begin:

To take advantage of the Bluetooth for Chevrolet functionality, you must first pair a Bluetooth-enabled phone to a Bluetooth-enabled vehicle.

Note: If you do not pair a Bluetooth-enabled phone, all calls will be made using OnStar® Hands-Free Calling.3

Some additional tips:

1. You can pair up to five phones with your 2009 Silverado.
2. Your system automatically recognizes the first phone you pair. To use a different paired phone, you must
select it using the "Change Phone" command.
3. Only one paired cell phone can be connected to your system at a time.
4. When the vehicle is in motion, you cannot pair a phone.
5. Pairing should only need to be completed once (unless changes to the pairing information have been made, or the
phone is deleted).

4. Your system will respond with a "Bluetooth ready" message
followed by a tone
5. Clearly say "Pair"
6. Your system will respond with instructions and a four-digit

this PIN on your phone

Begin the pairing process on your phone:

connected
3. Your system will ask you to confirm your name
4. If you confirm that name, the system will respond with the
message: "'<Phone name>' has been successfully paired"

i know turn on the bluetooth from the settings

then your phone is not compatible

The order in which you turn on the two devices seems to make a difference.

This is a common problem with the LG when trying to connect to many other devices, not just the TomTom.

Uninstall every BT software you have and any Nokia PC Suite software you have. Plug in your BT phone dongle and let windows auto recognize the device. after it is done installing, then put in the Nokia cd. Do it in this order.

hi!!!!!!!!!
try to configure out first the router!!!!
may be it has network password or security key

Go to the Menu -> Settings -> Connection and there we have the second option to pair a device. Cheers
