[iGO - Street](https://kb.hemamaps.com/hn7-legacy-unit?hsLang=en#igo-street) # iGO - ETA times don't seem to be accurate **This article applies to the following Navigator model(s):** - HN5i - HN6 - HN7 - HX-1 If you start routing, you may see that the Arrival Time & Time Remaining to get to your destination may be innaccurate. It's important to understand that these indicators are approximate only. They should be relatively accurate but they may not be exact. Also, it is important to understand that the choice of vehicle profile in iGO can have a major impact on the times calculated. For example, a route may be calculated to take 1:40 in default car mode, but if you change your vehicle profile to the default truck profile, the same route may take over two hours. This is because the default truck profile MAXIMUM SPEED is set to 80 km/h by default. The maximum speed of 80 km/h will affect the calculation of the time taken to complete the route. Be wary of changing your vehicle profile in the route settings as this can affect the times shown. - [Hema Nav - 2026 August Updates](https://kb.hemamaps.com/hema-nav-2026-august-updates?hsLang=en) -
