Please, note that, tha database in the releases (Q1, Q2, Q3 and Q4) may be different in here databases and iGO maps. I found that through the years helping here maps, so some roads may be present in here database in some release (Q1 2011 for example) and the same roads may be missing in iGO map from the same release (Q1 2011 for example).
For example, here in Bulgaria, we added 2-3 roads that appeared in here database in Q1 2016 release, but the same roads appeared in iGO map in Q3 2016 release. This differens is from the time that passes until NNG buy maps data, compile it and make oun map release.
