K750i bluetooth handsfree problem with TomTom GO

Posted by smeg24
Hi,

Just got a branded k750i from Vodafone and tried to connect to TomTom GO 500 for handsfree. The devices pair together OK and the TomTom can dial out OK but when trying the voice call I get no sound from the TomTom or the phone and the caller can't hear anything.

I've tried looking around for similar problems but couldn't find any thing SE support said could be an issue with BT V2 in the K750.

Anyone got any technical jargon I can give SE support so they can look into providing a firmware update? What do you reckon on the chances of SE looking into this instead of simply saying its TomToms problem ? (It works fine with my old T610 and Nokia 6230).

Thanks.

When you did the paring did you go "Bluetooth-My devices-New device" and then the paring?
Is so try removing it and paring again but this time go "Bluetooh-Handsfree-My Handsfree-New Handsfree"

Might work, it solved my problem with bluetooth headset (jabra250v)...

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.

thanks!

UPDATE 9/21/05-----------------------
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:
----------

Unfortunately, you are using an incompatible device. The W800i is not compatible with the GO 700. The T630, K700i, P910i are compatible but not the W800i. If you have any further questions, please contact us.

Latest reply from TomTom tech support ... not very helpful:

-------------------------

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/product[....]?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

Subject: Phones
Product: K750i

Opinion: please help. I can't get sound transfer into handsfree devices to work. I can pair, use all other functions, but no sound. I have updated the phone from your site: I am paired with TomTom Go 700 and Nokia HS-3W. I have tried every combination that i can find on the bluetooth headset set up on the phone.
Country: GB

Bought a Tomtom 500 yesterday - did not check compatability with SE 750i.

Looks like the Sony will have to be junked - there are more phone options than satnav.

My son's motorola worked without problem- so the Motorola V3 looks like an option for T-mobile in the UK, although the camera looks much poorer than the Sony. Has anyone used this combination?

This issue IS now resolved with the November 2005 update from the TomTom website.

Not before time...
