I'm curious about how the Garmin RV GPS units compare to the Rand McNally RV GPS's . . .
I have a Rand McNally RV5510 GPS, and while it has been pretty good so far, I've had it replaced twice.
I got it as a Christmas present on Christmas Day, 2012 . . . and that very day we left for our new 2013 Trail Runner's maiden voyage . . . and the unit was defective right out of the box.
The Camping World where Santa purchased it was about 10 miles from where we were staying, so the next day we returned it (thanks to Santa for providing a gift receipt
) and swapped it for another one.
It didn't come with the Lifetime Maps, so this past January before we left for the Arizona HOC Rally I purchased the Lifetime Maps ($90) and downloaded the past two years of updates and no problems.
A month or so later while I was doing an update, a message popped up saying that there was a new map update!
So when I finished the regular update, I unplugged the unit from the computer and turned it on . . . then turned it off and reconnected it to the computer.
It took about a half hour for it to download the new Map update . . . and when it was in the middle of installing . . . it crashed the unit and I got a 'corrupt device' message on the screen.
So I called the Rand McNally hotline, and they told me that since my unit was out of warranty that I was out of luck . . . which didn't sit well with me!
I then said to the RM person that had I known that the Lifetime Map purchase was going to crash my unit that I would have bought a new unit that included the Lifetime Maps instead of blowing my $90 for a download that not only did I get little use out of . . . but also damaged my unit as well.
She put me on hold for a few minutes, then when she came back she said that they would email me an RA number so that I could ship it back so they could fix it.
In the end, for some reason it was beyond repair, so it was replaced with a refurbed unit and my Lifetime Maps was transfered to it.
While I thank them for replacing my bad unit . . . this new one does not work as well as the old one.
It takes forever to boot up when I turn it on . . . and I have to touch the screen several times to get it to do what I ask of it.
