4.5 Tom Tom sat-nav a winner, worth every penny biglebowski | 13/06/2008 | See all biglebowski's reviews (10) This is one of the new slim line Go units. It has GB and Ireland full mapping and also in the box is the all the stuff to connect it in your car, a USB dock to connect to your PC, guidebook and CD with manual and PC software for Tom Tom Home. Note, you don't get a carry case or a mains charger, useful as those are, they are extras.Being a Go it has the larger screen, which in my opinion is worth paying extra for, as it is so much easier to read in the car when you quickly glance down at it.Anyone familiar with Tom Tom will feel right at home because the set up, menus and function is very similar to previous products. Those new to Tom Tom should remember that the accompanying book is a quick reference guide and you'll probably be referring to the fuller manual (PDF) on the CD. Tom Tom Home installs quickly from the disk.It is worth bearing in mind though that everything is pre-loaded on the Go and it'll work fine straight out the box. You never need to connect this to a PC if you don't want to. You'll miss out on a free safety camera update and of course the full manual, but that's about it really. It comes pre-loaded with stacks of Points of Interest (car parks, stations, tourist attractions, fuel, hospitals etc) which are really useful and you can enter a destination in several different ways, easy.If you're new to sat-nav/Tom Tom you'll be pleased to know that this unit is a breeze to set up and use. Almost everything on it is very intuitive and if you're unsure you can always log on for help on their website. It's very flexible to use, clear, simple and well thought out. Tom Tom have obviously put a lot of thought in to it to make it as user friendly as possible. Apart from on/off everything works off the touch screen, great, except if like me you sometimes have a sausage fingers moment just at the wrong time. The features, some more useful than others of course, are endless and I can't cover them all here.The main useful function improvements on this new range is better advance lane guidance, map share and using real averages to calculate journey times. Also there's some voice recognition stuff there although to be honest I think it's easier just to tap it in.You can connect your mobile to it via Bluetooth, so useful and safer hands free is yours and being a Traffic, once your phone is connected you can get traffic updates for your route. Whilst talking safety we ought to mention you can set it up to alert for safety cameras and also to display your speed, the current speed limit and a warning in the highly unlikely event that you would ever stray above the limit.Wirelessly connecting to your car audio system and attaching an iPod are also possible I think but untried by me.I have to tell you it is a brilliant piece of kit and whether this might be your first sat-nav or a replacement I'd recommend it without hesitation. The unit is much slimmer and lighter than the old one and the windscreen dock/mount much easier.Really my only gripe is the same as on the previous models, trying to get it to plan an alternative route the way you want to go rather than it wants to go can be a maddening and frustrating experience, but you usually beat it in the end. Oh and come on Tom Tom you should give us a free case in the box, that's just mean.Finally of course, remember, don't leave it in the car and hide away the connecting stuff.
