It only takes a few menu selections and button pushes to disable the
"road lock" procedure. The tough part is remembering the precise
sequence. Fortuantely for me, Garmin has .pdf file versions of the
owner's manual at their website for all the units that I have.

No matter whose system you buy, check first on line to see if they
have this handy feature. It may not make or break a particular
choice . . . but it is nice to have.

take care . . .
