I've had the original tom tom for many years now and have found it a godsend at times. same as securespark's the screen mount means you don't have to plug or unplug any lead to remove the unit.securespark said:I find TomTom awful.
A lot of my colleagues have it, and it often sends them down dead-end streets. Went out with one of the guys and from my house it tried to send him back to the main road via a street that has been severed since time immemorial!
I have Garmin C310 which I find good. It cost £175 a year ago. It has a screen mount that means you don't have to unplug the charging lead before removing the unit. It has two speakers for clearer sound: good for my deafness.
It is easier to enter the address details - some other satnavs require a space between the two halves of the postcode - a small point, but it niggles.
The only thing that bothers me is its shape. It is bulky, which means carrying it in pockets in awkward - you look like you have a strange bulge in your pants.
The "C" range of satnavs seem to be slowly disappearing, in place the Nuvi range is appearing.

All Satnav's are only as good as the maps supplied to them, usually by third party mapsellers and dependant on the user base for informing about changes or inaccuracies of said maps between releases.
I find the tom tom very easy to update with the latest Speedcams or other POI's which can't be said of some satnavs on the market, some are unable to be updated by the user.
In the end it's up to personal preference so i would suggest buying a satnav magazine guide and read it to help with deciding.
