Q. I am at an age where orientation plays major tricks on my mind. At times, when I am done shopping, I've forgotten where I parked. Is there a GPS device that will help me find my car? This device needs to be very user-friendly and simple.

A. We all need a little help finding our car from time to time. That's true no matter our age.

If you already have a GPS unit, you should be set. Add a waypoint in the GPS unit before leaving your car. Take the GPS unit with you. To find your car, navigate to the waypoint.

The steps for adding a waypoint vary. Manually adding one every time you park can quickly become a hassle.

Some GPS units automatically add waypoints when removed from their mounts.

Garmin makes a number of GPS units with this feature. They start around $400. Look for units featuring Garmin Locate. I could not find a similar feature from other manufacturers.

You needn't purchase a full-fledged GPS unit. There are GPS gadgets designed specifically to help you return to a location.

These gadgets are relatively inexpensive. They're also easy to use and small enough to attach to your keychain.
