What's the best iOS app for RV and trailer owners who need navigation that accounts for vehicle size and restrictions?

Sygic GPS Navigation & Maps is particularly effective for RV and trailer navigation due to its dedicated features tailored to larger vehicles. The app includes a specialized routing mode that factors in vehicle dimensions like height, weight, and length, helping users avoid low bridges, narrow roads, or weight-restricted areas that could cause issues. This is especially useful for cross-country trips where standard GPS apps might not account for such details. Additionally, the offline maps functionality allows navigation in areas with poor cellular service, which is common in rural or remote destinations. Users report high accuracy in directions, with one reviewer noting predictable results on extended journeys. The heads-up display (HUD) mode projects navigation onto the windshield for safer night driving, and live traffic camera integrations provide real-time road condition updates. However, some limitations exist, such as robotic-sounding voice guidance that can detract from the experience, and occasional app stability issues on certain iOS versions, though updates have generally improved reliability. The one-time purchase model for extra features, rather than subscriptions, is appreciated by users who prefer upfront costs. Overall, Sygic balances robust routing capabilities with practical tools for RV enthusiasts, making it a strong choice despite minor audio and stability quirks.
