Cadillac nav system

Look in your owners manual under navigation symbols. It makes reference to 3D mode. I looked at a 2008, but it is a bit different and I didn't have a 2010 to compare it to. I don't know the page to refer you to, as I am looking at service info online. I will include some of the info.

Navigation Symbols

The following symbols are the most common symbols that appear on a map screen.

Your vehicle is shown as this symbol. It indicates the current position and heading direction of the vehicle on the map.

The destination symbol appears on the map, after a route has been planned, marking the final destination.

The waypoint number displays on the map after a stopover has been added to your route.

A waypoint is a series of two or more marked stopovers on the way to the final destination. This feature allows you to add up to three waypoints to the current route, between your start point and final destination. Once a waypoint has been added, the points can be edited or deleted.

The distance to crosshairs indicates the distance to the crosshair area displayed on the map screen during map scrolling.

This symbol only appears when time is not available.

The distance and time to destination symbol indicates the distance and the estimated time remaining to the final destination or arrival time, depending on the option selected.

Press this screen button to change between viewing the time of day and the arrival time. If waypoints have been added to the current route, each waypoint destination appears giving the same information.

Select this screen symbol to switch between North Up, Heading Up, and 3-D
modes.
This north up symbol indicates the map with North Up, known as North Up mode. While in North Up mode, the vehicle icon follows the north direction on the map regardless of which direction the vehicle is traveling.

Select this screen symbol to switch Heading Up, North Up, and 3-D modes.

This heading up symbol indicates the map with the vehicle travel direction up, known as Heading Up mode. While in Heading Up mode, the direction the vehicle is traveling will always be at the top of the map screen. The shaded triangle indicates the North direction. The vehicle icon will always be headed in the direction the vehicle is traveling.

Press this screen symbol to change to 3-D mode.

The symbol for the 3-D function is the same as the Heading Up symbol, but shows the map in a 3-D view.

So the video that I should have watched, I finally got to. The vehicle that I saw was a 2006, not a 2010, so of course they are different. Your 2010 navigation system is exactly the same, as what is offered in the CTS-V. That is why the service literature, as well as the owners literature, groups them together. You have three choices of audio systems, option UAV, U2Y, and U2X, all are pretty much based on sound quality. It is hard drive based, so there is no map DVD to maintain. The radio is updated only by USB, or an update navigation map disc. The only other thing I can suggest is to get your salesman to demonstrate and make a comparison of one, for you.
