My recommendation: DO NOT BUY THIS spend some more money and buy a TomTom.

The unit is in very small pieces by the side of the road - where exactly? I have no idea. bonjour voila jai casse la carte sd de mon gps cartrek 400 et je nai pas le cd d instalation j aimerai pouvoir telecharger tous les parametre de la carte sd pour pouvoir les transferer dans une nouvelle carte que je vien d acheter ou trouver le logiciel de mon cartrek 400. I threw the unit to the floor from my window in utter fury after it had got me totally lost in London. This manual comes under the category navigators and has been rated by 1 people with an average of a 6.6. This is nothing to do with the signal being poor, my route in and out of work is fine - so how can it be a weak signal? It's not like a mobile phone! This unit just stops working as if the satallite just goes out of range (y'know, like in Patriot Games?) that's the only way I can describe it. View the manual for the CarTrek 400 here, for free. Routes can take 30mins to find often the route is never found. there are times when the signal just drops out and you have to turn it off and on again several times. Well, I don't know about those other people, but I wanted to use this to navigate around place where I had not been before and for this purpose, the Cartrek is rubbish. I bought the CarTrek cos it was just over 100quid from Savastore thinking 'what a bargain!' You're probably doing the same, looking at units like the TomTom and the CarTrek wondering 'what's the difference then?' and you're here looking for a review. I had used a friends TomTom one for a London trip and had a brilliant experience with it.
