A ha'penny worth of tar

  (Rating Hidden)

I was intending to replace my old TomTom XL (which due to old age I guess now takes about 60 hours to update its W Europe maps). Despite Which?'s reservations I was tempted by the enormous map coverage with the Go 400 and the free lifetime traffic...

Nothing new


Better looking desighn. You can fiddle with maps more. Screen size perfect. Not too big not too small G0500 is too big so I swapped it for go 400. Good traffic info.

Best One Yet!


I have owned many TomTom devices over the past 10 years but this device is easily the best to date. There are no longer expensive annual traffic subscriptions to pay for, the device uses your phones data allowance to connect to the Live HD Traffic...

Excellent GPS


Another great GPS from TOMTOM! Good value for money especially buying from Halfords offering best price on market and 20 pounds cash back from tom tom. GPS working fast and accurate extra bonus is free maps upgrades.

Easy to get on with


A nice simple unit to use and get on with. Good value extras with the half price deal on this let me buy the extended window mount which offers more flexibility on where you can put the sat nav.

solid unit, logical to use

So far so good


This device, like many other satnavs, seems to get qualified praise because of software, service and other issues. Well, I haven't used it on the road yet, but linked to the PC it seems to have done all the downloading and updating etc in good order...
