Conclusion: TomTom's One 140-S has more features than you'd typically expect from a $200 GPS device from a top manufacturer.
Pros: Includes maps and seven million POIs for the U.S., Canada, Puerto Rico, and Mexico. Text-to-speech conversion. Features advanced capabilities (IQ Routes, lane assist, multisegment routing) that are uncommon on entry-level devices.
Cons: Awkward mounting bracket. No SD card slot for map expansion. No Bluetooth phone interface. Live traffic updates aren't included.
