This is typical due to a power cord or power socket issue.. The Rand is likely to random freeze / lock up due to micro-vibrations in the incoming power connection. Gently squeeze the USB slightly so that the inner conductor strip is tighter when you plug it into the GPS socket. (SEE PICTURE) Also, always wrap the power cord once or twice around the mount neck to reduce strain. Finally, make sure that the cig lighter male end isn't getting loose or the fuse inside isn't loose and make sure that your lighter socket itself isn't loose and causing the power plug to vibrate out.
Those are (by far) the most common "locks and freezes" fixes to the Rand brand of GPS if your updates are current and you have no corrupt files. -
