I've have an '07 TL-S.
When I input an address into the nav system, the accuracy is pretty good...within 15-20 yds.
When I touch the little circle on the screen, sometimes it's WAY off, by maybe several hundred yards. I presume that when you do that, you're getting the location via GPS as opposed to the data base on the DVD.
Is that a normal deviation range? Can the dealer tighten it up some?
Thanks.
