Turns out the apple solution uses tom tom. Cant post a link but im sure you read this as it was announced WWDC today.
Wonder what this means for android version of tom tom.
In all the GPS tests using phone based software Tom Tom navigation always comes out far better than others .Routes are better road works and other delays are better .
Purchase would really depend upon the user and how often and where its going to be used .
The probability with this money behind it Tom Tom will improve further .
No reason for Tom Tom not to sell across all platforms .
Tom Tom + Apple the future could be a greater developed Siri incorporated within the navigation .
