I get a lot of search engine hits on a previous post about pairing the iPhone 3G with the TomTom Go 500, so this is just a quick blog post to confirm that the iPhone 4 (iOS4.1) also pairs with the TomTom Go 500.
SatNav maps are only as good as the map data on which they are based. Inevitably errors will creep in and roads change. TomTom GPS units have a feature called MapShare which ostensibly allows you to report any such errors to allow the maps to be corrected.
Since I got my SatNav five years ago, TomTom has shown a road in Horwich that has never existed. Unfortunately, despite reporting this error using MapShare (and prior to that directly to TeleAtlas, the map provider), this road is still shown on TomTom’s maps (updated today v845.2666):
This may well be a phantom road – a deliberate mistake put there by TeleAtlas to catch out anyone who decides to copy their maps. The problem is that the TomTom will try to use this road as a route. SatNav units often come in for some stick when they route drivers down none-existent roads, but if the suppliers fail to fix these errors, despite being told about them several times, it is hardly surprising.
