I have the Garmin StreetPilot - brilliant piece of kit, no experience of the tomtom. For those who reside in N.Ireland, as I do, the tomtom is useless, as it uses TeleAtlas mapping software, whereas the Garmin uses Navteq and their maps are more advanced and have better coverage here.
Do yourself a favour and have a look at the mitac mio 269.It has almost the same specifications as the tom tom 700 but is much cheaper.I can heartily recomend this as i recently drove to southern spain using the mio269 to guide me on non toll roads all the way.ALL roads for GB and Europe are built in on the hard drive. Major and Minor.
In June, I got one of the first TomTom 700`s available in the UK, just in time for my holiday in France.
I travelled about 2300 miles, and found it invaluable. Yes, I did find a couple of mapping errors, but nothing is perfect. It is easy to set up, plan a route, and gets a satellite fix very fast. The speed of route recalculation is remarkable, when you deviate from the original route.
The bad point is that the screen can be difficult to see in bright sunshine. Previously, I used an Ipaq with TomTom Navigator 3, which was very bright and clear. Unfortunately, this version did not allow the option to avoid toll roads.
Obviously, you already know that you would only need the 700 if you want full European mapping.
I don`t use the bluetooth phone connection, but I would guess that you will pay for any time you are connected. Could possibly prove expensive, but it depends on the connection time length, and your tariff.
The price of £499.89 is expensive, but its about £49 less than I paid at a retail outlet in June.
