Not possible! And also, why on earth do you want to do that? Sygic and iGO have the same map provider (Tomtom), therefore map coverage with the latest maps is identical.
A very good point.
But there are use's out there that want to reinvent the wheel.
It is hard enough getting one or the other GPS program to work 100%.
Let alone try to switch maps from one GPS to another.
Then there is the question why would you even want to do that????????
Plus this is the Garmin section not Sygic!!!!!!!!!!
