I have used the google navigation feature for a while now, i used it when the UK work around was fully functional, and i have used it couple of times since it was released for the uk offically.

It seems to work fine in gprs only areas, so long that you dont use satalite pictures, and stick to using only the normal maps, also it seems to download a large catchment area around your current route, so even if you loose signal completly you'll likely pick it up again before you run out of map.

All in all a great app adds significant functionality to my phone.

It was briefly available when Navigation was first launched and then even more briefly via a hack - then I was trying out on the rooted G1 I had at the time. Now with the Nexus One and the Car Dock it is very good for what it is - 3G coverage and satellites not withstanding!

About time. Hopefully that will allow vodafone to release the nexus one at last.

The idea of needing a 3g connection is a joke though. pretty useless

TomTom now only provide the most basic functions built-in with their 'TomTom' speed traps, new maps and voices all have to be paid for separately whereas they were once free.

I suspect that all these services will become free again soon. Either that or a new Bill through Parliament protecting TomTom's monopoly

Just give Mandy a call: £5000 a day to prop up an ailing business model. Money well spent!

as you say having a gps system relying on the 3g network is pretty much a joke , it may work in central london ,but there is no way you could rely on this for any serious journey
