I believe jgalar and I are on the same page.
I create a waypoint called PK where the vehicle is parked or if I am going to be dropped off and the vehicle leaves I will call it DP1 for Drop Point 1.
When your unit has a satellite fix you can press the Rocker/Mark in and hold for a second to create the Waypoint. A Waypoint screen will come up and you will want to edit it. By scrolling around the page using the Rocker you can highlight the different boxes. On the top Left is the symbol box. You can select different symbols that have meaning to you. At a drop-off point I use the Hiker Symbol. Where the vehicle is going to be parked I use the Pickup symbol.
When you want to return to your vehicle or drop off point go to the Main Menu page, select the Find Icon, and then the Waypoints Icon. Your nearest waypoints will popup: select the one you want. Select the Go To option in the lower right corner of the page. A popup will give you two options Follow Road and Off Road. If you are out in the bush you will select Off Road, which is the direct route. On selection the map page will appear showing a path to your waypoint. You can start walking the path and the pointer will start moving to the waypoint. Another option is to follow the Compass Pointer on your Compass Page.
I suggest that you have your unit in the Track on Mode. To setup the track function go to Main Menu, and select the Track Icon, from there a page appears with a few options. To start with keep it simple. I have the Wrap when Full box checked.
Under Record Method I have selected Auto. In the Interval box I have defaulted to Normal. It is critical that you select a color to show on your screen. I normally use, Green, Blue, or Red. I believe that gives the best contrast on the screen. The Transparent option is transparent.
The Track gives me a number of options when returning. I can just turn around and watch the Position Arrow (you) follow the Track back.
A second option is to go to the Track Page and move from the On to the Off Option. Using the Rocker, select Save. The Track will be saved and by default it will give the date or you can name it. You can use the current color or select another color. The key is that you want to check the Show on Map box. The next step is to select the TracBack box. The Map with your track shows on the screen with a White pointed curser. Place the white curser on the Waypoint you want to return to.
