Connects to bluetooth for a second and then shows disconnect

Unable to connect my new iphone to the bluetooth in my car.
I've turned off the blue tooth in my old phone but it only turns off the bluetooth in the car. I have tried to then reconnect my new iphone, which is searching and showing that it has located the bluetooth (blue tooth flashing in car, shows on the sceen for a second and then turns off with message 'no service' phone off. If I turn on the old phone, everything comes back on.
Any ideas?

1-Your tom tom does not have the device driver needed to connect to your phone?
2- Turn off the bluetooth device the tom tom is a bluetooth device and the two of them are probably arguing the tom tom and your actual bluetooth.
3- You have to put the tom tom in discover mode and let the PHONE find the tom tom then the tom tom should find the phone, once this happens you enter the code and tell the phone that this is a trusted device. The same thing that was done with your actual bluetooth device. Hope this helps

Try disconnecting the bluetooth device then turn the bluetooth off then hold the power button untill the bluetooth shows a solid red light then try connecting the bluetooth between your palm and the bluetooth device hope this helps

Remove the SD card

The card needs to be formatted properly first that's all,

formatting is better done in a card reader.

Right click on it and select format select FAT32 as the files system

Update your device without the SD card.

Make sure your GPS runs OK without the SD card

Now re-connect the tomtom but don't let tomtom home run. exit TTH if need be.

You now ned to select your tom tom which will also show as a drive.

In windows explorer select tools then folder options.

Click view and tick the box for "show hidden files and folders"
It may warn you but you can ignore it.

then just copy ALL the files from the tom tom to your sd card

DO NOT USE CUT AND PASTE !

Once all the files are on switch off the tom tom and insert the sd card and re-boot
It should now work again

Any help with this as mine (530) is doing the exact same?

Hi, I got round this problem by pressing and holding the ON/OFF button for 15 seconds untill system reboots. Then reconnect mobile,if not delete mobile and repeat process.

Most Motorola mobile phones can only remain discoverable by other Bluetooth devices for a period of 60 seconds. Occasionally this period is too short to complete the pairing process with a TomTom device.

Try here some phone features are not supported via tomtom

Have you tried using 'other wired device', try each com, rather than bluetooth, on tomtom configuration settings, works for me with TT5 and a Holux BT GPS reciever
