Cannot authenticate maps 2460LMT


After downloading version 2012.40 I get the message Cannot authenticate maps on my 2460LMT.

The error message still shows and the GPS firmware shows 2.89 which is the same as when I started. Any more suggestions before calling Garmin?

Called Garmin and finally got to tech support who downloaded the maps again using option 2. Another rep tried to fix problem before the download. Map download takes 9 or 10 hrs

I'm having same problem.

I'm having same problem. There seems to be many options. What was option 2 that worked for you?
