Just bought the xl325se at Wal-Mart on Black Friday. I already did a Windows Explorer full backup of the device before connecting it to Home as advised. Now afterwards when I connect to Home and use the LMG on the File menu, it says I have the latest map! This is wrong I think because my device says installed map is version 835.2423. I thought the latest map was 840.xxxx How do I get it to give me the latest map? Any help anyone would be greatly appreciated.
