I need a decent GPS app that has better US maps than the free ones have.
This is to be used in places like rural NH which the free ones (like Waze & Google) ignore...or get totally wrong & make you go on cow paths instead of roads !!

I'm hoping there's an app that has decent voice guidance that I can easily install via simple side-loading.

Questions:
- Is there a clear/easy guide (Sygic for dummies ??) to help folks like me get through the confusing extra steps to make the Sygic stuff work ??

- Is there some other really good GPS app with voice that may get me through the rural areas so that I don't get lost anymore !!

Thanks for any help with this stuff.
