Pros: Makes a good paperweight or doorstop.

Cons: Clicking noise coming from the drive does not follow a regular pattern, preventing its use as a metronome. Also SMART showed a failure right from the box, and it would not format.

Overall Review: SMART showed a failure right from the start, was any QC done?

Pros: Worked for 1 year for a half dozen trips

Cons: no free map updates, Failed while i was in the middle of nowhere when used less than a dozen times with a flashing red X 2 weeks after the warranty expired. Unhelpful tech support if you can even get through to them. $10 if you want updated maps. Told me to turn onto a bike path, directions sometimes take you on ridiculous detours.

Overall Review: Pass this one and get a cell phone with navigation or a model that is more reliable and has free map updates.
