TomToms are being updated not much is changing aside from the appearance?
There seems to be
some agreement that most of the changes will be available on the previous gen models
via software upgrades, not sure whether if you buy a TomTom after the updates are released whether a charge will still be involved?
I think the only real hardware difference between the 530/730 and the previous models maybe EPT (Enhanced Positioning Technology,)
if it's included? EPT deals with the loss of signals due to tunnels/High Buildings, which may or may not be an issue for you?
Latest TomTom (and some other) deals
here. Also lists cheapest reconditioned prices for TomTom units.
There are also a bunch of savings at
Amazon on the One and One XL ranges, I presume on the back of new units coming out next week, apologies if this has already been posted.
