I have the RVND7 which I believe was new last year. Used it for my trip to Florida last year and it worked fine. Last year it would not download GS trip router but I think that may have been changed.
The only thing I did not care for was the fact that it seemed to notify you of POIs at the last moment making it difficult to exit the interstate safely. Really not a problem if you pay attention to the signs along the road telling you what is at the exit, but would be nice if trying to plan ahead.
