Conclusion: Garmin's impressive nüvi 1690 integrates connected services and offers plenty of routing options, but the high price and mandatory ads—even when you're not using said services—are turn-offs.
Pros: Accurate directions. Slick software design. Google-powered services are a boon. Solid traffic reporting. Useful elevation readings.
Cons: Bundled data subscription expires after two years. Displays ads. Still requires extra-cost map updates like any other GPS. Connected services not integrated with main POI database. On-board EDGE radio caused GSM buzz in our car stereo.
