I wanted to like this product. The screen is bright and easy to operate with a refreshing UI. But it's severley let down by very poor software and limited features that feel like they've really gone for style over substance here. I've used various TomTom sat navs for years and yes their software and especially support has always been poor, but when they worked, they worked brilliantly with traffic rerouting being one of their strongest areas. However this iteration is a huge step backwards to the point of unusability. So I've returned mine and stuck with an older model while I look at other options.
Pros: - speed and responsiveness. Now moves in almost real time with the car. No lag. - UI is great and makes others look really dated.
Cons: - you need to 'tether' your mobile, they don't make this clear. This means turning on Personal Hotspot for iPhone (other smartphones have a similar function) as well as Bluetooth. This drains battery and is also subject to restrictions of your network as some phone companies disable it or charge extra to turn it on. - very buggy software (e.g. current version doesn't allow you to connect an iphone so no live traffic and it also reboots randomly far too often) - lots of useful features removed from previous models (no avoid road block option etc) - you'll have to wait for future updates to reintroduce features, if at all. - TomTom support; as useful as a chocolate teapot.
If they manage (and it's a BIG if) to restore features and fix the software then I might return to TomTom, but for now you must avoid this current crop of models. Pick up one of their Via or previous year's model instead.
