I'm moving to the lower 48 next summer so the NAV would do as advertised. As a canuck I'll have to pay cash in the USA, but at least $8k will be in my pocket. I did the toyota builder for both countries and retail for the TE is 41,800 US or 49,500CDN!
Looks like I might have to go to the USA to get mine. The Cdn TE's don't come with NAV, but at least they come with an added value feature of an extra 8k on the price tag!
