Hi, I have a few suggestions for improvement. It would be great if I could filter the map to show only the selected truck stop brand, instead of seeing all brands at once. Also, the map data needs more frequent updates to stay accurate. Lastly, it would be very helpful if traffic light locations could be displayed on the map for better route planning and safety. Thanks for considering this.

Thanks for the feedback, it will be relayed to our dev team for future improvements! In the meantime, you can adjust what's displayed during navigation with the following steps: Menu > Display > HUD (Toggle on/off desired categories).

This was ok when it was free and I'd continue using it if there were ads or something, but it isn't worth $5/mo. It frequently freezes when navigating (data bars irrelevant) and only *usually* avoids non-truck routes. It never did try to send me toward a low bridge, at least. It also doesn't differentiate between California blue vs black routes. I tried to bring this up to customer service but they kept telling me how to customize my settings. we went in circles lol. Clueless and disappointing.

I've been using Hammer for more than seven years, and it has been an invaluable tool for long-haul journeys. Its clear display and straightforward interface made it easy to use, even on busy roads. The routing capabilities were impressive, consistently providing efficient and practical paths for commercial vehicles, with accurate bridge heights and road restrictions. Overall, this GPS significantly improved my confidence in any city 💯💯
