Unlike the above models, the TomTom Go50 has a resistive screen, which means supporting "strong" and the entry to take effect.
When you switch your smartphone to the GPS, you feel to break the screen to write!
The screen is still very readable, matte default shows a map with buildings modeled in 3D.
Without being of Google Maps, the result is nice.
Geolocation and routes are good, no surprise about that.
** For cons, involving traffic, it will set it all to become eligible.
Already, it will register Tomtom, register the device, activate the service (and for that matter, send the updates).
Once done, you must enable tethering 3g / 4g / bluetooth on your smartphone, then to pair with GPS.
Thus, the GPS will use the connection 3g / 4g phone to retrieve real-time information.
That's good, but it can be tedious to set up, and it finally consumes little battery in the phone.
So, with this system, you will have the traffic in the country of your SIM card (or else you're going to get turned into "data abroad").
The "traffic" is officially free for life, and the "radar" is offered for 3 months (remaining less than the competition)
Once everything is in place, it works very well.
The advantage of this type of device is for me to preserve the battery from the phone, and above all to properly use GPS even when there is no GSM network.
Small flat on navigating through the menus: this is not at all intuitive, even if you eventually find it.
Good value for this model, but for a few euros more, so take a GO 500 has a capacitive screen, much easier to use.
In conclusion remains to be seen holding in time.
