I tried to update my maps on my 1350 last night to 2012.40. When my gps is hooked to the computer the garmin site says I have 2012.40 loaded, but he map info says it's still 2012.20. The maps are installed on a sd card. 2012.40 is on the card. The old map is not. Why is the gps telling me I have an old map?
