I'm looking at a low mile 2014 4wd 1500 Ram that is currently in the US but was originally sold new in Canada.
I'm told the factory warranty is voided being from Canada, the seller knew that when he bought it and bough a supposedly good aftermarket warranty.

Is buying a truck like this a bad idea?
Any other issues I should be aware of?
Can the navigation system be activated in the US?

Thanks.
