Go 700 Bluetooth problems

I recently bought a go 700 but am dissapointed to find it will not work correctly with my Sony Ericsson K750i phone. The phone pairs with the TomTom Ok and will download address book etc. but on making and receiving calls there is no audio transferred. TomTom just say that this phone is "not supported". I think this is a very poor response. If some of the advanced functions didn't work this could be forgiven but basic bluetooth functionality of handsfree operation should be compatible with all bluetooth phones.
Has anyone else had similar problems?

Hi all,

Yes I am having the same problem. I have a SE W800i with T-mobile in the USA, along with a TomTom Go 700.

They pair without problems.
I can dial a phone number from the TomTom without problems.
I can download the phone book into my TomTom without problems.

HOWEVER...
After establishing a call, I cannot get any audio on the TomTom, nor can they hear me.

With the W800i, once in a call you can hit the "More" option button, and then select "Transfer sound" option to send audio to the TomTom. However, even after doing this I get absolutely no sound. Worse, after selecting "Transfer Sound" the w800i is unable to re-establish a link with the TomTom ... not sure if the problem is with SE or TomTom.

I did find the email address of the TomTom USA President: Jocelyn.Vigreux@tomtom.com

I suggest we all email him and ask for help in resolving this issue, as TomTom support has never gotten back to me!

Here was what Sony-Ericsson has to say. Looks like the W800i support BT2 and maybe that's why we are having compatibility issues:

AND HERE WAS TOMTOM'S REPLY:

Bluetooth coding within each Bluetooth stack is different between devices and manufactures. Because of these differences, not all Bluetooth devices are compatible to connect to any other device using Bluetooth. The engineers in Amsterdam have tested this devices and it is not compatible. There are no specifics as to why. If you want a phone that is compatible, please stick to the compatibility list here: http://www.tomtom.com/products/section.php?ID=77&Section=107&Language=4. These are phones that are compatible and can support if you were to run into any configuration problems. If you have any further questions, please contact us.

Kind Regards,

TomTom USA Customer Service

Tarrant,

Thanks for that info. I have just had a reply from TomTom stating that the K750i is not compatible with the 700 (Shame they didn't state that on their press advertising that their product only works with certain phones)
