I purchased a Good Sams 7735LM in December. Just used it on a two month road trip. Hope you didn't purchase one. Worst GPS you could get. It does not like left turns unless there is a dedicated left turn lane with a traffic light. Sent me out of my way by 14 miles because of this. Had many other similar left turn issues. Twice sent me past the campground, told me to make a U turn and come back so I could make a right into the campground. It also does not like if you don't follow its exact route and will try to route you back to the point you deviated from (ie: stop for gas 100 miles down the road heading north and it will send you back 100 miles south) If you did purchase ths unit, please be aware of the problems. Rand McNally will do nothing for you.
