hands free kits - back to the future.

I have been simply using my mobile with a hands free which is built into my sat-nav in my car.
But the sat-nav is too far away on the dashboard so there is a lot of background noise so I have to shout and customers can not hear me that well - That is not very professional. I have bought a blue-tooth earpiece - a version which says that on one AAA battery it will standby for six months - cool. but it is no use: it disconnects at random and does not automatically reconnect again. So when that vital call comes along it could be lost. I will take it back to Argos today and buy a different one.
I don't like those that stick right in the ear : I want to hear as well!

Can anyone explain why Sandra (my sat nav) adds the word colliers after every time she says High street - "A two hundred and eighty four, High Street Coliers" I cant see any coal merchants around!

My Tomtom sat-nav is ridiculous. In an attempt to make it do everything, it is packed with features, some of which are highly annoying and possibly dangerous. It contains lists of police stations and doctors - but only Irish ones. So my nearest doctor is 300 miles away on the irish coast !. It is also possible to dial 999 accidentally with a couple of touches. Because it is touch sensitive, these screens are easily accessed by accident when you are handling it. So on several occasions I have accidentally dialed up Irish police stations and chemists and on 2 occasions the emergency 999. Is there a word for this over-stuffing of features and gadgets ? Worse still it appears impossible to disable this feature alone and disable this feature without disabling the whole blue tooth connection. This thing is out of control! Sooner or later I think my sat-nav will try to take over the entire world ? Does yours ever spout out in an Irish accent "Its yer sat naav , Turn the bloody ting off!" I suppose next time I prog it to get me home, it will say "I noo where yooo live!' And how are we supposed to drive to Ireland from England? - It will be directing me over the cliff edge lemming fashion before briefly alerting me - whilst falling through thin air - that I have exceeded the speed limit, that there is a hazard ahead, and that the nearest undertakers is Kilblarney. "Connecting you now to book an appointment".
