Ok, I've been around for some time, and have read like all the posts on this subject, but I still have no clear answer. Which should it be on USA or INTL? Whats the down fall for using one over the other? Is there really that much of a difference (time wise), or could one really effect if I get a ticket or not? I'm sick and tired of kinda worrying about it, I wanna know the truth!!!!! I reseted my detector to see what version it was, it was the 4.5 and the default is set on INTL. I need to know which one I should use! Thank you for anyone that clears it up for me and gives me a striaght up answer!!!!!
