Bought a TomTom Go Live 1000 recently, wasn’t exactly cheap but way better than the 8 year old one it replaced. Looked around at the time and alternatives all had some issues or were too much hassle to get hold of.
It’s not been perfect though, randomly rebooted quite frequently although subsequent software updates have nearly fixed this. The lane assist thing is a bit hit and miss to, given it’s only about 50% accurate you can’t trust it so it’s rendered a bit pointless.
I’d not had traffic updates before and couldn’t see much point (I don’t need a sat nav for commuting and don’t do a whole lot of miles) but it’s great, giving a much more accurate predicted journey time and warning of upcoming jams etc. (it’s not exactly real-time though, probably a 15-30 minute delay on updating info).
It has the new magnetic power connection to which is much less faff than the old mini-USB one. The mount is a big improvement to (although my old was was a few generations ago when it was still a spit and stick design ;p
