I have this one Tomtom Rider.

best features
Tomtom route planer enables you to log in to tomtom maps via any PC and plan your route. It is now very easy to use. You can then save your route to a file for future use, send it via email, or send it via Bluetooth to your device.
You can share routes also directly from your GPS via Bluetooth. I often sit at work and log onto tomtom route planner create routes and save them. Then next time I turn on my GPS they are there ready to use.

Bad features
Screen/font size too small. I find the street names too small to read sometimes and you can not change the font size.
This unit is waterproof however last summer after one huge rainstorm mt GPS fogged up. They replaced the whole unit no problems because it was still under warranty but I have yet to put this one under the same rain conditions.
good luck hope this helps
