I have a Tom Tom Go 550 (or something like that).
It has Bluetooth, so can be used as a hands free for your phone.
Google search is handy – google a business for example, it finds it and gives you the option to ring it, or be directed there.
Live Traffic is ok, but can be hit and miss – it has diverted me round some very big delays, but isn’t always running on real time – it can also divert you onto side roads that are sometimes equally busy.
The odd road map isn’t always up to date (I paid for an update recently and it still doesn’t show some roads that have been around for 5-6 years)
Overall I’d recommend it as a good product though and I don’t think it’s ever got me lost. The layout of the maps are nice too.
