Looking at getting SatNav for my car which im getting soon 
I'm getting a new phone on an upgrade which can handle TomTom Mobile 5 and i can buy a BT GPS device.
Is this any good or should i plump out for a NavMan 510 or similar?
I'm not a lover of the TomTom units as they are big compared to the Navman's but how does it fair on a phone?
Thanks,
Andy
