Hi and thank you for your question. My name is ***** ***** I will be happy to assist you.
On your device, from the main menu, select setup, then select map, then select Map information/select map. This will show all the maps that are loaded on your device. Find your map you need and enable it.
Please let me know if you are able to find it. If not, please let me know and we will continue to troubleshoot.
