There are some nice upgrades on the 910 like a bigger screen, hard drive and additional Plus Services, but overall, for the price I paid, the Go 700 is one heck of a GPS unit and quite a nice add-on to my car. You can read some great reviews on TomTom’s GPS systems, as well as many others over on GPSreview.net. TomTom has some great extra “Plus services” that come along with the purchase of their units. Many of the services require pairing the GPS unit with your phone via Bluetooth…. The phone WILL successfully pair up with the Go 700 (you might have to try a few times) and if you have a service plan like Cingular’s MediaNet (I have the unlimited), then you will be able to connect to TomTom’s Plus services and download updates, get traffic and many more services. You will NOT however be able to connect to the Go 700 and use it as an external speaker/mic for the Treo 650. Basically you won’t be able to use *any* normal bluetooth features, like pairing it with your headset, while in DUN mode…. The unit comes with an internal database of millions of POI’s and you can add additional POI’s by downloading them via the net, or through TomTom’s website, as well as directly via the Plus services via that bluetooth connection on your phone…. And if you get tired of the voices that ship with the unit, you can add additional voices, available via a variety of websites out there.
