I have read some good reports about the RV Garmin 770 here and other places, so I purchased one yesterday. Put in all my particular, height, weight, lengthy, etc. So far on the first 24 hours of use ...
Mine is terrible, just got back from a 7000 mile trip out in the southwest, it was wrong about 60% of the time, used the iPhone most of the time comparing the two. What a waist of money Rich
