Frequently Asked Questions

Yes. Google Maps does not account for truck height, weight, length, or hazmat restrictions. A wrong turn onto a low bridge or restricted road can result in thousands of dollars in damage, fines, and lost time. Truck GPS devices are a safety requirement, not a luxury.
Update maps at least every 3 months. Road construction, new restrictions, and bridge changes happen constantly. Both Garmin and Rand McNally offer over-the-air updates — set a reminder to check monthly.
Yes, both devices can switch between truck and car routing profiles. However, truck routing will choose different roads than car routing, often preferring highways over shortcuts. Switch to car mode for personal use.
