We purchased a Rand McNally RVND7 GPS when we first got our coach in 2017. It has been a good little unit getting us to where we needed to be at the end of the day. With the GPS rollover in April 2019 we started having issues with times, speeds and other little annoyances. I was just about to buy a new GPS and decided to look on the RM website to see if they had come up with a download to fix the problem - no joy.
However, you can request repair of the device by calling RM. I did and to my surprise they fixed it - for free. I was emailed a UPS label on the same day I called, 17 Sept, sent it in on the 18th and got it back today with new software. The unit works like new.
If you were caught up in the GPS rollover then contact RM - the are great.
