I'm not sure if this is possible, but I have been using the Pioneer navigate HUD with iGO Primo (UK&IRL). Now I am back home I was wondering how run in Aust. The HUD relies on an in-app purchase only available for Europe maps - so doesn't work with iGO Aust app ( I've tried). I've jb iPhone & moved the HUD Lync file and anything else I thought might be HUD related to Aust app but no joy. HUD only recognizes UK app. So how do I do the reverse - move Aust map to UK app? I've added fbl, poi & dem - but still no success. Advice appreciated.
