Buying Guide: Key Purchase Considerations
- Map updates and coverage: Look for lifetime or free updates and whether maps cover the U.S., Canada, and Mexico, plus options for additional regions if needed.
- Vehicle-specific routing: If you drive a truck, RV, or tall vehicle, choose devices that optimize routes based on height, width, and weight.
