I appreciate that radio frequency interference (RFI) can be a problem and that it's been suggested that River Park doesn't endorse the use of an extension cable.
The diagnostics that the RM tech support agent asked me to run this morning didn't show any corrupted files on my SD card. I haven't had a chance to put the SD card back into the Xite head unit to confirm operation.
I did delete the Dock software and re-installed it. During that re-installation, the \NaviMaps\DCA.x.xx.SDL files were overwritten and now show a "Date Modified" of today. I'm optimistic that all is good now.
Although I don't share your concern about RFI, thanks for the suggestion.
