Garmin Unveils 1st Navigation Device for RVers

I bought my last GPS, a Garmin 176C, back in 2003. I've wanted to update for some time now but haven't found what I was looking for. The Rand McNally 7720 is nice but I can't preplan a trip on the PC, upload it to the GPS, and then afterwards save the trip back to the PC for posterity. Nor can I use Easy GPS to upload/download a route. I asked Garmin last year if they had plans for a 7" RV unit and they said no. Liars! I'm out of here. I have to go order my new RV 760LMT.
