I picked up a new 140S last night, my wife has pretty much taken over our other TT fulltime. I learned from last time to back it up before trying to download the newest map. My first try to update aborted saying I needed 32MB more space, so off I go deleting the computer voices of languages I don't need, freeing up over 100MBs. The 2nd try was still going when I went to bed. I got up a while later to check on it to see that there was a file error on a ".dat" file, again aborting the map update. After this failed attempt I got the dreaded "map npt found" error so I just did a restore. Things are working fine now, but I still don't have the newest map. How do I tell what version my map is and the version of the newest one, andif it is really worth the trouble? I know the map doesn't show the shopping center and all the new lanes that were put in across the street from my work about two years ago.
