GM GPS SD Cards for North America

This category is for GM GPS SD cards with North America navigation map coverage. The cards here are used in GM SUVs and trucks with factory navigation, including popular models such as Acadia, Canyon, Sierra, Terrain and Yukon. All products are physical GPS SD cards with preloaded maps for the USA, Canada and, on some versions, Mexico.

What GM GPS SD Cards Do

Each GM GPS SD card stores the navigation maps that your factory head unit uses for route guidance. Instead of reading map data from an internal drive, the system reads it directly from the SD card inserted into the navigation slot.

In daily use the update process is simple:

• remove the existing SD card from the slot,
• insert the new GM GPS SD card in the same place,
• switch the ignition or the unit back on and let the system load the updated maps.

On most GM systems the unit recognises the replacement card by itself. The first time you use it, you may see a short message on the screen confirming that new navigation data is available.

Latest Available North America Navigation Maps

The GPS SD cards in this category carry the latest available North America navigation map releases for the supported GM platforms. They are aimed at drivers who still use the built-in navigation and want to keep it useful, instead of driving with map data that is several years behind.

Depending on the card, coverage can include:

• USA and Canada, or
• USA and Mexico.

The exact region is listed on each product page, so you can choose the map update that matches where you actually drive.

Because GM uses the same navigation platforms across several models, one GPS SD card can often be used in more than one vehicle. In practice the cards in this category are commonly used in GM and GMC SUVs and trucks such as:

• Acadia,
• Canyon,
• Sierra,
