To be honest I have never used the handsfree part of my TomTom. Mind you it is hardly surprising the quality of the send audio is so bad.
You would normally mount the unit very close to the windscreen so the distance between your mouth and the mic in the TomTom is rather more than is optimal. And I seriously doubt that the mic in the TomTom is that good either. On the 510 the mic is a minute thing buried deep inside the top of the unit with a 1mm hole to let the sound in!
The pro audio engineer in me tells me this is not a recipe for good audio quality. Even a "proper" hands free kit can struggle and that is with the mic mounted in a far better position in most cases.
Though to be fair my unit did come with a separate plug in mic with a tie clip attachment (bit like the things you see presenters wearing on the telly) which would probably improve matters no end. I just can't be arsed to set it all up
And the
IAM member in me says you should not be using the phone whilst driving anyway, handfree kit or not
Most of the
Plus services are subscription, except the weather. Though I did get a free Speed Camera subscription when I got my 510. But then that was part of a special bundle from Currys which included the useless TMS receiver (picks up a signal broadcast by some radio stations in the RDS system - or at least it is suposed to, mine never seemed to work!) so I can't be sure if that was part of the deal.
Though I don't use the TomTom Speed camera database anyway. I have a free lifetime subscription to the
PocketGPS World camera database. Which I find is better than TomTom's. And the subscription is cheaper (even if you DO have to pay for it unlike me

)And if you submit a camera location to them you too can get it free
